While running the psconfig wizard I got following error message. SQL Server at SharePoint 2013 has an unsupported version 10.50.1600.1. Please refer to …..
The SQL version 10.50.1600.1 is SQL server 2008 R2 RTM version.
The SQL version should be on Service Pack 1 to successfully run the configuration wizard for SharePoint 2013
You can download the SQL R2 Service pack from here http://www.microsoft.com/en-us/download/details.aspx?id=26727
Once the Service Pack for SQL is installed, please run the SharePoint 2013 psconfig wizard again and this time it should run successfully
