-Migration Strategy
-==================
-
-This document details an in-place migration strategy from ML2/OVS to ML2/OVN
-in either ovs-firewall or ovs-hybrid mode for a TripleO OpenStack deployment.
-
-For non TripleO deployments, please refer to the file ``migration/README.rst``
-and the ansible playbook ``migration/migrate-to-ovn.yml``.
-
-Overview
---------
-The migration process is orchestrated through the shell script
-ovn_migration.sh, which is provided with the OVN driver.
-
-The administrator uses ovn_migration.sh to perform readiness steps
-and migration from the undercloud node.
-The readiness steps, such as host inventory production, DHCP and MTU
-adjustments, prepare the environment for the procedure.
-
-Subsequent steps start the migration via Ansible.
-
-Plan for a 24-hour wait after the reduce-dhcp-t1 step to allow VMs to catch up
-with the new MTU size from the DHCP server. The default neutron ML2/OVS
-configuration has a dhcp_lease_duration of 86400 seconds (24h).
-
-Also, if there are instances using static IP assignment, the administrator
-should be ready to update the MTU of those instances to the new value of 8
-bytes less than the ML2/OVS (VXLAN) MTU value. For example, the typical
-1500 MTU network value that makes VXLAN tenant networks use 1450 bytes of MTU
-will need to change to 1442 under Geneve. Or under the same overlay network,
-a GRE encapsulated tenant network would use a 1458 MTU, but again a 1442 MTU
-for Geneve.
-
-If there are instances which use DHCP but don't support lease update during
-the T1 period the administrator will need to reboot them to ensure that MTU
-is updated inside those instances.
-
-
-Steps for migration
--------------------
-
-Perform the following steps in the overcloud/undercloud
-~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
-
-1. Ensure that you have updated to the latest openstack/neutron version.
-
-Perform the following steps in the undercloud
-~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
-
-1. Install openstack-neutron-ovn-migration-tool.
-
-   .. code-block:: console
-
-      # yum install openstack-neutron-ovn-migration-tool
-
-2. Create a working directory on the undercloud, and copy the ansible playbooks
-
-   .. code-block:: console
-
-      $ mkdir ~/ovn_migration
-      $ cd ~/ovn_migration
-      $ cp -rfp /usr/share/ansible/neutron-ovn-migration/playbooks .
-
-3. Create  ``~/overcloud-deploy-ovn.sh`` script in your ``$HOME``.
-   This script must source your stackrc file, and then execute an ``openstack
-   overcloud deploy`` with your original deployment parameters, plus
-   the following environment files, added to the end of the command
-   in the following order:
-
-   When your network topology is DVR and your compute nodes have connectivity
-   to the external network:
-
-   .. code-block:: none
-
-      -e /usr/share/openstack-tripleo-heat-templates/environments/services/neutron-ovn-dvr-ha.yaml \
-      -e $HOME/ovn-extras.yaml
-
-   When your compute nodes don't have external connectivity and you don't use
-   DVR:
-
-   .. code-block:: none
-
-      -e /usr/share/openstack-tripleo-heat-templates/environments/services/neutron-ovn-ha.yaml \
-      -e $HOME/ovn-extras.yaml
-
-   Make sure that all users have execution privileges on the script, because it
-   will be called by ovn_migration.sh/ansible during the migration process.
-
-   .. code-block:: console
-
-      $ chmod a+x ~/overcloud-deploy-ovn.sh
-
-4. To configure the parameters of your migration you can set the environment
-   variables that will be used by ``ovn_migration.sh``. You can skip setting
-   any values matching the defaults.
-
-   * STACKRC_FILE - must point to your stackrc file in your undercloud.
-     Default:  ~/stackrc
-
-   * OVERCLOUDRC_FILE - must point to your overcloudrc file in your
-     undercloud.
-     Default: ~/overcloudrc
-
-   * OVERCLOUD_OVN_DEPLOY_SCRIPT - must point to the script described in
-     step 1.
-     Default: ~/overcloud-deploy-ovn.sh
-
-   * UNDERCLOUD_NODE_USER - user used on the undercloud nodes
-     Default: heat-admin
-
-   * STACK_NAME - Name or ID of the heat stack
-     Default: 'overcloud'
-     If the stack that is migrated differs from the default, please set this
-     environment variable to the stack name or ID.
-
-   * PUBLIC_NETWORK_NAME - Name of your public network.
-     Default: 'public'.
-     To support migration validation, this network must have available
-     floating IPs, and those floating IPs must be pingable from the
-     undercloud. If that's not possible please configure VALIDATE_MIGRATION
-     to False.
-
-   * OOO_WORKDIR - Name of TripleO working directory
-     Default: '$HOME/overcloud-deploy'
-     This directory contains different stacks in TripleO and its files. It
-     should be configured if TripleO commands were invoked with --work-dir
-     option.
-
-   * IMAGE_NAME - Name/ID of the glance image to us for booting a test server.
-     Default:'cirros'.
-     If the image does not exist it will automatically download and use
-     cirros during the pre-validation / post-validation process.
-
-   * VALIDATE_MIGRATION - Create migration resources to validate the
-     migration. The migration script, before starting the migration, boot a
-     server and validates that the server is reachable after the migration.
-     Default: False
-
-   * SERVER_USER_NAME - User name to use for logging into the migration
-     instances.
-     Default: 'cirros'.
-
-   * DHCP_RENEWAL_TIME - DHCP renewal time in seconds to configure in DHCP
-     agent configuration file. This renewal time is used only temporarily
-     during migration to ensure a synchronized MTU switch across the networks.
-     Default: 30
-
-   * CREATE_BACKUP - Flag to create a backup of the controllers that can be
-     used as a revert mechanism.
-     Default: True
-
-   * BACKUP_MIGRATION_IP - Only used if CREATE_BACKUP is enabled, IP of the
-     server that will be used as a NFS server to store the backup.
-     Default: 192.168.24.1
-
-   * BACKUP_MIGRATION_CTL_PLANE_CIDRS - Only used if CREATE_BACKUP is enabled.
-     A comma separated string of control plane subnets in CIDR notation for the
-     controllers being backed up. The specified subnets will be used to enable
-     NFS remote clients connections.
-     Default: 192.168.24.0/24
-
-   .. warning::
-
-      Please note that VALIDATE_MIGRATION requires enough quota (2
-      available floating ips, 2 networks, 2 subnets, 2 instances,
-      and 2 routers as admin).
-
-   For example:
-
-   .. code-block:: console
-
-      $ export PUBLIC_NETWORK_NAME=my-public-network
-      $ ovn_migration.sh .........
-
-5. Run ``ovn_migration.sh generate-inventory`` to generate the inventory
-   file - ``hosts_for_migration`` and ``ansible.cfg``. Please review
-   ``hosts_for_migration`` for correctness.
-
-   .. code-block:: console
-
-      $ ovn_migration.sh generate-inventory
-
-
-   At this step the script will inspect the TripleO ansible inventory
-   and generate an inventory of hosts, specifically tagged to work
-   with the migration playbooks.
-
-
-6. Run ``ovn_migration.sh reduce-dhcp-t1``
-
-   .. code-block:: console
-
-      $ ovn_migration.sh reduce-dhcp-t1
-
-
-   This lowers the T1 parameter
-   of the internal neutron DHCP servers configuring the ``dhcp_renewal_time``
-   in /var/lib/config-data/puppet-generated/neutron/etc/neutron/dhcp_agent.ini
-   in all the nodes where DHCP agent is running.
-
-   We lower the T1 parameter to make sure that the instances start refreshing
-   the DHCP lease quicker (every 30 seconds by default) during the migration
-   proccess. The reason why we force this is to make sure that the MTU update
-   happens quickly across the network during step 8, this is very important
-   because during those 30 seconds there will be connectivity issues with
-   bigger packets (MTU missmatchess across the network), this is also why
-   step 7 is very important, even though we reduce T1, the previous T1 value
-   the instances leased from the DHCP server will be much higher
-   (24h by default) and we need to wait those 24h to make sure they have
-   updated T1. After migration the DHCP T1 parameter returns to normal values.
-
-7. If you are using VXLAN or GRE tenant networking, ``wait at least 24 hours``
-   before continuing. This will allow VMs to catch up with the new MTU size
-   of the next step.
-
-   .. warning::
-
-      If you are using VXLAN or GRE networks, this 24-hour wait step is critical.
-      If you are using VLAN tenant networks you can proceed to the next step without delay.
-
-   .. warning::
-
-      If you have any instance with static IP assignment on VXLAN or
-      GRE tenant networks, you must manually modify the configuration of those instances.
-      If your instances don't honor the T1 parameter of DHCP they will need
-      to be rebooted.
-      to configure the new geneve MTU, which is the current VXLAN MTU minus 8 bytes.
-      For instance, if the VXLAN-based MTU was 1450, change it to 1442.
-
-   .. note::
-
-      24 hours is the time based on default configuration. It actually depends on
-      /var/lib/config-data/puppet-generated/neutron/etc/neutron/dhcp_agent.ini
-      dhcp_renewal_time and
-      /var/lib/config-data/puppet-generated/neutron/etc/neutron/neutron.conf
-      dhcp_lease_duration parameters. (defaults to 86400 seconds)
-
-   .. note::
-
-      Please note that migrating a deployment which uses VLAN for tenant/project
-      networks is not recommended at this time because of a bug in core ovn,
-      full support is being worked out here:
-      https://mail.openvswitch.org/pipermail/ovs-dev/2018-May/347594.html
-
-
-   One way to verify that the T1 parameter has propagated to existing VMs
-   is to connect to one of the compute nodes, and run ``tcpdump`` over one
-   of the VM taps attached to a tenant network. If T1 propegation was a success,
-   you should see that requests happen on an interval of approximately 30 seconds.
-
-   .. code-block:: shell
-
-      [heat-admin@overcloud-novacompute-0 ~]$ sudo tcpdump -i tap52e872c2-e6 port 67 or port 68 -n
-      tcpdump: verbose output suppressed, use -v or -vv for full protocol decode
-      listening on tap52e872c2-e6, link-type EN10MB (Ethernet), capture size 262144 bytes
-      13:17:28.954675 IP 192.168.99.5.bootpc > 192.168.99.3.bootps: BOOTP/DHCP, Request from fa:16:3e:6b:41:3d, length 300
-      13:17:28.961321 IP 192.168.99.3.bootps > 192.168.99.5.bootpc: BOOTP/DHCP, Reply, length 355
-      13:17:56.241156 IP 192.168.99.5.bootpc > 192.168.99.3.bootps: BOOTP/DHCP, Request from fa:16:3e:6b:41:3d, length 300
-      13:17:56.249899 IP 192.168.99.3.bootps > 192.168.99.5.bootpc: BOOTP/DHCP, Reply, length 355
-
-   .. note::
-
-      This verification is not possible with cirros VMs. The cirros
-      udhcpc implementation does not obey DHCP option 58 (T1). Please
-      try this verification on a port that belongs to a full linux VM.
-      We recommend you to check all the different types of workloads your
-      system runs (Windows, different flavors of linux, etc..).
-
-8. Run ``ovn_migration.sh reduce-mtu``.
-
-   This lowers the MTU of the pre migration VXLAN and GRE networks. The
-   tool will ignore non-VXLAN/GRE networks, so if you use VLAN for tenant
-   networks it will be fine if you find this step not doing anything.
-
-   .. code-block:: console
-
-      $ ovn_migration.sh reduce-mtu
-
-   This step will go network by network reducing the MTU, and tagging with
-   ``adapted_mtu`` the networks which have been already handled.
-
-   Every time a network is updated all the existing L3/DHCP agents
-   connected to such network will update their internal leg MTU, instances
-   will start fetching the new MTU as the DHCP T1 timer expires. As explained
-   before, instances not obeying the DHCP T1 parameter will need to be
-   restarted, and instances with static IP assignment will need to be manually
-   updated.
-
-
-9. Make TripleO ``prepare the new container images`` for OVN.
-
-   If your deployment didn't have a containers-prepare-parameter.yaml, you can
-   create one with:
-
-   .. code-block:: console
-
-       $ test -f $HOME/containers-prepare-parameter.yaml || \
-             openstack tripleo container image prepare default \
-                   --output-env-file $HOME/containers-prepare-parameter.yaml
-
-
-   If you had to create the file, please make sure it's included at the end of
-   your $HOME/overcloud-deploy-ovn.sh and $HOME/overcloud-deploy.sh
-
-   Change the neutron_driver in the containers-prepare-parameter.yaml file to
-   ovn:
-
-   .. code-block:: console
-
-      $ sed -i -E 's/neutron_driver:([ ]\w+)/neutron_driver: ovn/' $HOME/containers-prepare-parameter.yaml
-
-   You can verify with:
-
-   .. code-block:: shell
-
-      $ grep neutron_driver $HOME/containers-prepare-parameter.yaml
-      neutron_driver: ovn
-
-
-   Then update the images:
-
-   .. code-block:: console
-
-      $ openstack tripleo container image prepare \
-           --environment-file $HOME/containers-prepare-parameter.yaml
-
-   .. note::
-
-      It's important to provide the full path to your containers-prepare-parameter.yaml
-      otherwise the command will finish very quickly and won't work (current
-      version doesn't seem to output any error).
-
-
-   During this step TripleO will build a list of containers, pull them from
-   the remote registry and push them to your deployment local registry.
-
-
-10. Run ``ovn_migration.sh start-migration`` to kick start the migration
-    process.
-
-    .. code-block:: console
-
-       $ ovn_migration.sh start-migration
-
-
-    During this step, this is what will happen:
-
-    * Create pre-migration resources (network and VM) to validate existing
-      deployment and final migration.
-
-    * Update the overcloud stack to deploy OVN alongside reference
-      implementation services using a temporary bridge "br-migration" instead
-      of br-int.
-
-    * Start the migration process:
-
-      1. generate the OVN north db by running neutron-ovn-db-sync util
-      2. clone the existing resources from br-int to br-migration, so OVN
-         can find the same resources UUIDS over br-migration
-      3. re-assign ovn-controller to br-int instead of br-migration
-      4. cleanup network namespaces (fip, snat, qrouter, qdhcp),
-      5. remove any unnecessary patch ports on br-int
-      6. remove br-tun and br-migration ovs bridges
-      7. delete qr-*, ha-* and qg-* ports from br-int (via neutron netns
-         cleanup)
-
-    * Delete neutron agents and neutron HA internal networks from the database
-      via API.
-
-    * Validate connectivity on pre-migration resources.
-
-    * Delete pre-migration resources.
-
-    * Create post-migration resources.
-
-    * Validate connectivity on post-migration resources.
-
-    * Cleanup post-migration resources.
-
-    * Re-run deployment tool to update OVN on br-int, this step ensures
-      that the TripleO database is updated with the final integration bridge.
-
-    * Run an extra validation round to ensure the final state of the system is
-      fully operational.
-
-Migration is complete !!!

-Infrared plugin to carry out migration from ML2/OVS to OVN
-==========================================================
-
-This is an infrared plugin which can be used to carry out the migration
-from ML2/OVS to OVN if the tripleo was deployed using infrared.
-See http://infrared.readthedocs.io/en/stable/index.html for more information.
-
-Before using this plugin, first deploy an ML2/OVS overcloud and then:
-
-1. On your undercloud, install openstack-neutron-ovn-migration-tool package (https://trunk.rdoproject.org/centos9-master/component/network/current/)
-   You also need to install python3-neutron and python3-openvswitch packages.
-
-2. Run ::
-   $infrared plugin add "https://opendev.org/openstack/neutron.git"
-
-3. Start migration by running::
-
-   $infrared  tripleo-ovn-migration  --version 13|14 \
---registry-namespace <REGISTRY_NAMESPACE> \
---registry-tag <TAG> \
---registry-prefix <PREFIX>
-
-Using this as a standalone playbook for tripleo deployments
-===========================================================
-It is also possible to use the playbook main.yml with tripleo deployments.
-In order to use this:
-
-1. Create hosts inventory file like below
-[undercloud]
-undercloud_ip ansible_ssh_user=stack
-
-2. Run the playbook as:
-ansible-playbook main.yml  -i hosts -e install_from_package=True  -e registry_prefix=centos-binary -e registry_namespace=docker.io/tripleomaster  -e registry_localnamespace=192.168.24.1:8787/tripleomaster -e registry_tag=current-tripleo-rdo

-Usage:
-
-  Before running this script, please refer to the migration guide for
-complete details. This script needs to be run in 5 steps.
-
- Step 1 -> ovn_migration.sh generate-inventory
-
-           Generates the inventory file
-
- Step 2 -> ovn_migration.sh reduce-dhcp-t1 (deprecated name setup-mtu-t1)
-
-           Sets the DHCP renewal T1 to 30 seconds. After this step you will
-           need to wait at least 24h for the change to be propagated to all
-           VMs. This step is only necessary for VXLAN or GRE based tenant
-           networking.
-
- Step 3 -> You need to wait at least 24h based on the default configuration
-           of neutron for the DHCP T1 parameter to be propagated, please
-           refer to documentation. WARNING: this is very important if you
-           are using VXLAN or GRE tenant networks.
-
- Step 4 -> ovn_migration.sh reduce-mtu
-
-           Reduces the MTU of the neutron tenant networks networks. This
-           step is only necessary for VXLAN or GRE based tenant networking.
-
- Step 5 -> ovn_migration.sh start-migration
-
-           Starts the migration to OVN.
