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:
but that change would be for the 3.7.0 right?
