Thank you Tim,

i just tried it and it's true, many user settings which were lost before 
are now restored after i migrated the mysql databases "roundcube" and 
"kolab" onto the new server. I was afraid of some breaking SQL-changes 
between 3.3 and 16.1 but it seems to be compatible :)

Thank you for your hint regarding the Sieve directory, i had migrated it 
already together with the imap store and it's already working like a 
charm.

So far everything seems to work, very good.
Now I have to do some intense testing before deploying the new server.

Cheers
Thomas
