We know that our Service Manager 2012 SP1 customers would be waiting for this, so here it is!
Service Manager 2012 SP1 now officially supports Service Pack 2 for SQL Server 2012 with Update Rollup 6 installed. The SQL server 2012 SP1 is going out of support in the month of July this year, hence the Service Manager 2012 SP1 deployment owners can now upgrade their SQL servers to 2012 SP2 after installing UR6 from here.
We have done a fair amount of validation to make sure that everything continues to work as expected. That said, if there is anything which seems suspicious let us know via your comments below.
