=== Known issues
* Upgrading to 7.9.0 from an earlier version will result in incorrect mappings
on the {ml} annotations index, and possibly also on the {ml} config index. This
will lead to some pages in the {ml} UI not displaying correctly, and may prevent
{ml-jobs} being created or updated. The best way to avoid this problem if you
read about this known issue before upgrading is to manually update the mappings
on these indices in your old {es} version _before_ upgrading to 7.9.0. If you
find out about the issue after upgrading then reindexing is required to recover.
Full details of the mitigations are in
{ml-docs}/ml-troubleshooting.html#ml-troubleshooting-mappings[Upgrade to 7.9.0 causes incorrect mappings].
