Cassandra Targett commented on SOLR-15718:
------------------------------------------
> However, there may be other reasons to upgrade to 8.11 before a rolling
> upgrade to 9.0
There's at least one scenario already documented where one must be on 8.10
before going to 9.0:
https://nightlies.apache.org/solr/draft-guides/solr-reference-guide-main/major-changes-in-solr-9.html#upgrade-prerequisites-in-solr-9
(there might be others on that page, I just remembered this one off the top of
my head).

> In SOLR-14095 (Solr 8.5) a system property {{solr.useUnsafeOverseerResponse}}
> was introduced to do rolling upgrades from 8.5 to 8.6 (which lets 8.6 fall
> back to Java-serialization).
> See [https://github.com/apache/solr/search?q=useUnsafeOverseerResponse]
> When upgrading to 9.0 I suppose we tell people to first upgrade to 8.11, so
> in 9.0 we don't need this. [~tflobbe] agree?
