Skype for Business In-Place Upgrade failed with "Unsupported version of SQL Server detected"

I came across a problem a customer reported while he tried to upgrade an Lync 2013 Standard Server to Skype for Business Server.

The error is:

Before this server can be upgraded, the following must be resolved:
An unsupported version of SQL Server was detected. The local RTCLOCAL instance should be Microsoft SQL Server 2012 Express Edition SP1 or later. More information on downloading....
The local LYNCLOCAL instance should be Microsoft SQL Server 2012 Express Edition SP1 or later....
First let me remind, that you have to follow this upgrade steps: 
  • Install CU5+ latest hotfix to Lync 2013 topology
  • PowerShell RTM version (6.2.9200.0) or later
  • Have at least SQL server 2012 SP1 installed
    SP1 (
    download), SP2 (download)
  • Operating System Hotfixes:
Out of the Box, Lync Server 2013 installed the SQL 2012 Express Edition RTM.


Now if you only install SP1, make sure you updated both instances RTCLOCAL and LYNCLOCAL.

Next, please ensure your CU Update is installed correctly.
You MUST patch you database. Read the instruction very carefully (LINK):

Install-CsDatabase -ConfiguredDatabases -SqlServerFqdn <SE.FQDN> -Verbose
If you simply for got, which is very very very often the case, you run into issue and it is very hard to support this. Mostly we MVP also forget checking all Lync Server if you have patch the Server since beginning correctly.
