Cyrus will automatically update the index format when you first open
a mailbox using a newer version of any Cyrus program (imapd, pop3d,
lmtpd, whatever).  This applies both when upgrading a mailbox "in place"
or when the files have been copied to a new server via XFER.  The
in-place upgrade should be able to handle index files from all earlier
versions of Cyrus, not just the most recent - so you can upgrade all the
way from 2.2.12 to 2.3.16, even though it's about 3 revisions of index
later!

The mailbox will be fine on the new server - you just can't transfer
it back.
