That is not entirely accurate,
When you mention "unless you made a backup of your KDE 4.6
data" It sounds like alot of trouble. Backups like these should be made any 
time you are moving from a stable system to the next big thing.

In reality only 1 file (kmailrc) seems critical (to me) in this case, perhaps 
backups of around a dozen files would allow you to restore things w/ no 
trouble at all.

I "upgraded" to kde sc4.7 with excitement about moving to kmail2 in 
particular. Before the "upgrade" I read up a tiny bit on the kmail2 
migration tool. Hoping for the best I started kmail (kmail2) and followed 
the prompts. FAIL, read more, try again FAIL. Rinse and repeat until bored.

I was not surprised (or worried as I had made backups) by these failures, 
tried a couple of fixes but no go. My mail setup just has to much going on.
Lots of folders, thousands of saved messages, filters, POP and IMAP accounts.
I wasn't surprised that the migration tool failed.

All of this is a long way of saying, although the migration may fail, 
returning to the 4.4 series of kmail is not difficult.

Kmail 2 creates its own folder... ~/.kde4/share/apps/kmail2 so that does not 
interfere w/ the older kmail (~/.kde4/share/apps/kmail). 
Kmail2 does not alter (at least in my case) your mail folder. (I keep my 
	mail in ~/Mail). 
I don.t remember if ~/.kde4/share/config.kmailrc is the same for both apps or 
not, but this file should be backed up when you have working configs anyway.

To return to the orig kmail (4.4 series) all I had to do was 
	temporarily add the kde4.6 repo to yast,
	perform the downgrade, (only kdepim related apps, mail, organizer, etc) 
	Once downgraded, I locked the versions for those (approx) 10 apps, 	
	removed kde4.6 from my repo list, restored kmailrc from my backup. 
	Good to go

Actually I did find a problem, (I suspect that) configuration changes I made 
in Akonadi while setting up Kmail2 overwrote my working configuration. I 
could recieve mail, but somehow my send configurations had gotten BORKED. I 
could have tracked down the backups of these configs as well, but 
reconfiguring 3 email accounts to properly send mail wasn't that difficult 
either.

Just wanted to clarify, returning to the tried and true kmail4.4... is not 
terribly difficult at all. In fact it was probably easier than writing this e-
mail :-)

Oh and BTW, Nepomuk has been spamming my .xsesseon-errors file for quite 
awhile as well. I don't remember, but I think turning nepomuk off in 
systemsettings may reduce this problem.
