I am considering installing scalix 12.5 from scratch and migrate few mail boxes from very old 11.3 version with sxmboxexp (running it on 11.3) and sxmboximp (running it on new 12.5 installation).
I don't want to update the whole scalix server.
I care only about users mail folders and messages.
Does anybody know if it's possible ? Has anybody done such "migration" ?
