I just wanted to keep a note in the feature request list about supporting a way to
update from version 2.3.x to a current release without the need for an unconstrained
I/O storm caused by the forced mailbox format upgrades. We are still using version
2.3 because an update to 2.4 would cause mailboxes to be converted on first access.
If we could upgrade the replica first and then make it the primary after the
upgrade had completed and then upgrade the replica to complete the process, we
could do it. Alternatively, if the new version could use the old version of the
mailbox, we could then control the format update I/O usage.

(stuck on version 2.3)
