Special charm procedures
|
|
========================
|
|
|
|
The OpenStack charms are designed to accommodate every supported series and
|
|
OpenStack release wherever possible. However, upgrades (of either of the three
|
|
types) may occasionally introduce unavoidable challenges. For instance, it
|
|
could be that a charm is replaced by an entirely new charm on a new series or a
|
|
new charm is needed to accommodate a new service on a new OpenStack release.
|
|
These kinds of special procedures are documented here:
