Upgrading to Train on a deployment with a large database may hit
`bug 1862205`_, which results in instance records left in a bad
state, and manifests as instances not being shown in list
operations. Users upgrading to Train for the first time will
definitely want to apply a version which includes this fix. Users
already on Train should upgrade to a version including this fix to
ensure the problem is addressed.

A fix for serious `bug 1862205`_ is provided which addresses both
the performance aspect of schema migration 399, as well as the
potential fallout for cases where this migration silently fails
and leaves large numbers of instances hidden from view from the
API.
