This one is quick but interesting. You may run into an error “WMI Provider Error: Cannot find object or property” during SQL Server migration, in particular when switching SQL Service account from Source to Target.
I was recently working on migration from Exchange 2010 to Office 365 using DMM 8.11. I have installed DMM AD/Exchange console on computer1 and had a dedicated agent host computer2 to host my Mage agents.
During computer migration upon it joins the Target Domain, you may experience the following error trying to log in: “The security database on the server does not have a computer account for this trust relationship”
