Hi, is anyone aware of any program that I could run to upgrade a mailbox file structure from version 6.8 to the latest 12.x? I will be running a staged upgrade from the old version to the new one (moving over some domains, not all) and would like to upgrade the domains 1 by 1 and carefully since I'll be moving from SM 6.8 running on Windows Server 2003 to SM 12.X on Server 2012 R2. Thanks.
