Here are the implemented migrations:
-* *From V5 to V6* : Goal is to no longer rely on an UDT partition key for mailboxPath tables. Entries will be migrated
-to mailboxPathV2 table relying on a composite primary key.
-* *From V6 to V7* : Goal is to populate mapping_sources projection table. This table allows finding the source of a given redirection, which is
-handy for things like mail aliases (I want to list aliases rewritting things to bob). Without this projection table being available,
-(ie we rely on schema version 6 or less) such information is obtained through a full table scan, unoptimized. From schema version 7,
-the optimized projection can safely be used.
-* *From V7 to V8* : Add UID_VALIDITY to mailboxPath table in order not to mandate mailbox table reads.
Review comment:
Hmmm did we ever test versioning in our antora doc yet? That could be a good candidate to start :)

+JIRA: https://issues.apache.org/jira/browse/JAMES-3578
+
+Concerned products: Distributed James, Cassandra-guice James server
+
+In an effort to simplify the code base, we dropped support for Cassandra schema version prior version 8.
+
+Installation running older schema version than version 5 needs to rely on releases 3.6.x to upgrade to schema version 8,
+before upgrading to an eventual newer version.
Review comment:
ah actually you mention it here :) But I guess we need to mention it in the Antora doc too, probably safer...
