Hi

Wanting to upgrade our site database from 2008 R2 to 2012 SP2

Getting the error

Configuration Manager requires Microsoft SQL Server ......

You must upgrade SQL Server before installing Configuration Manager.

Any ideas?  I'm moving to SQL 2012 SP2, so it meets requirements

Did you follow a guide like this one ?

Make sure you are installing 64 bit SQL

I am performing as per guide mentioned

SQL Server 2012

version 11.0.5058

It isn't 64bit however

Hi,

Configuration Manager requires a 64-bit version of SQL Server to host the site database.
