I would do the following:
0. Make a tarball of the local maildir.
1. Write a new offlinerc for newserver.
2. Make a first sync (mostly empty).
3. Untar the archive to the updated maildir of newserver.
4. Have fun with nametrans rules.
5. Sync again to have local mail on newserver.
6. Live happily ever after.
In the past, I've migrated my mails from one server to another this way.
