[Dovecot] duplicate transaction log sequence?

We had to move our dovecot from one server to another and used rsync to move the
mail but it took us some time..
In our log at the new server, we are getting a lot of these..:


2010/10/08 23:28:23 imap(emailadr): Error: Index

Should I be worried, what does those mean? Is there something I must/should/can
do to fix it?


Also getting a lot of these..:

Those are just warning but should I do something with these as well?


And more like these..:

This looks kind of severe?


BTW, when moving from old server to new we upgraded Dovecot from 1.2.x to
2.0.5...

I guess you mean you ran it while users could still be making changes?

Those should go away automatically. Don't worry about them.

Message's flags were changed between two rsyncs, so the same message got
transferred twice but with different filenames. Dovecot now created a
duplicate message (since it thought that it's safer to create a
duplicate than to delete a non-duplicate).

They go away automatically too. Users might be annoyed at the duplicate
messages.

All of the index errors will go away too.

I should some day try to fix this I guess..

The next time you could do it with dsync to avoid these kind of
problems.
