SQL account change

What all would be involved in changing the SQL account from a local account with admin privileges to a domain account and what would be the potential issues?

I think this would be different depending on what version of DocuWare you are on.

This would be for Version 7

Pretty new to 7 and you will want to double check but you should just be able to create the domain user in MSSQL and make sure mixed Auth is turned on. The user will need the DB.creator role at least. Then sign into docuware admin tool and change the login to the new login for each database. I am not sure if there is still a settings file for each service like before that has this in it too..
