[Dovecot] Upgrading from 0.99.10.5 to 1.1

Hi,

I am upgrading a setup from Dovecot 0.99 to 1.1. There are a bunch of .imap.index* files that it appears that I can just delete, and they will be recreated as dovecot.index* files. Right?

Next, there are some .customflags that I have now learned are not being converted to dovecot-keywords (as we skipped the 1.0 version, and the conversion code appears to be removed in 1.1). Is there some way to convert this? Is it just a rename?

Thanks, Anders.
