Our customer is on TMS 14.3 and we need to upgrade them to TMS 14.6.2
They are currently running a local instance of Windows SQL Server 2008 Express (10.00.4000).
The release notes say that SQL 2008 R2 Express and SQL 2012 Express are the supported versions for 14.6.2.
I have tried upgrading to SQL Server 2008 R2 Express, however the installer does not give me the option to upgrade the SQL Server 2008 tmsng instance I am having trouble upgrading this on the customers TMS Server.
Has anyone done this before successfully and are there steps on how to upgrade to SQL 2008 R2 Express (or SQL 2012 Express)?
EDIT I've tried following the instructions here https://technet.microsoft.com/en-us/library/jj134439%28v=ws.10%29.aspx
I do not get a Select Instance Option
