TL;DR; Guidance on moving SharePoint SQL Server databases to a new server using DNS redirection, aiming to simplify migration and minimise downtime and manual effort.

SharePoint requires SQL Server. That’s a given, but what if you want to move the SQL Server databases to another server? TFS is easy enough to move between servers, but SharePoint is NOT. The only answer I can find is to do a full backup and restore from SharePoint, which takes time and effort.
The Plan
I will use a local SQL server with a named instance of “EPDev”, but I will also use a DNS name for the server “dpdata.ep-dev.[domain].biz”. This will allow me to, hopefully, move the databases without having to spend the weekend doing it. I should be able to backup and turn off the SQL server. Re-point “dpdata.ep-dev.[domain].biz” to the new SQL Cluster and restore the databases to the “dpdata.ep-dev.[domain].biz/EPDev” instance on that server. Then I will bring up the SharePoint server. This should work, but I have not as yet tested it…
Hopefully this will not screw up, but I will take steps to provide for that
probability possibility…
Microsoft: if you are listening, please make moving a SharePoint database as easy as TFS!
