6.4.4 which should work fine for IMAP<->Maildir, but has been reported
to be flakey with IMAP<->IMAP.

1) Sync to make sure things are reasonably similar
2) Drop in the latest OLI code
3) Change the account section to status_backend = sqlite
4) A new sync will convert your plain text cache to an sqlite cache (but
leave the old plain text cache around for easy reverting)
This should be quick and not involve any mail up/downloading.
5) See if it works :-)
6a) If it does not work, go back to the old version or set
6b) Or once you are sure it works, you can delete the
.offlineimap/Account-foo/LocalStatus folder (the new cache will be in
the LocalStatus-sqlite folder)
