I just migrated from POP to IMAP and I encountered three problems. Firstly, if you use nnmail-split-fancy-with-parent and still have your old POP (nnfolder) mail groups lying around, Gnus recognizes if new mails refer to a mail you have in you old archive, but tries to split them into a mailbox on the IMAP server with the same name as the group the parent is in on the old backend. This is temporary, but can be a bit confusing at first. Secondly, I had a few problems with moving my nnfolder mail archive to the IMAP server; approximately one in 500 messages could not be copied. I got several error messages. A few were caused by incorrect headers (which you can just delete by editing the message), but most errors were due to non ASCII characters in the message bodies. Especially, the \201 character seemed to cause trouble. What usually helped was first moving the message to the same nnfolder group is was already in and then trying to copy it to the IMAP server. If that didn't work, editing a message (e) and saving it (C-c C-c) worked for me as it removed the troublesome characters. Thirdly, it took quite some time to move all my archived messages to the IMAP server. I had to go into every group (C-u RET), select all messages (M P b), and move (B m) them an IMAP group. With the number of mail groups I accumulated over the years, this took quit some time. I would be nice if there were an easier way to do this. Maybe there is, but I just don't know about it.
