Point Imaged/Cloned Sharepoint 2010 to different/renamed SQL 2012 server - what needs to be changed/edited?

Newbie here... I am using our development VM's one has SP 2010 installed/working and configured and the other is SQL 2012 housing the DB's for the working SP sites and a third running IIS and hosting the pages.  I want to use clones to copy to additional VM's, rename the SQL and rename the SP 2010 (the IIS will stay the same just add the cloned site to it. MY question is "Is there an automated way of reconfiguring SP 2010 to point to the new SQL server? (I've already figured out how to change the SID information and run the queries on the SQL, just need info on the SP 2010 part.)

Thanks,

Jon P.
