I use 5 POP accounts and 1 IMAP and I see no dataloss issues. I have
some strange things related mainly to filtering, and then the most
irritating problem that address autocompletion went missing between
4.10.1 and ..2 .

It has been quite a while since I migrated and your method, to me, looks
complicated. I set up an "empty" KMail, created my accounts and manually
imported my existing mailfolders that I had moved to a backup.

The migrator is known to have problems.

Best regards,
Sinclair
