As the format of the "sqlcontext.xml" has changed, after the upgrade is complete, copy your settings to the new "sqlcontext.xml", then rename yours to sqlcontext.xml.old, and the new one to sqlcontext.xml.


1) open sqlcontext.xml, and sqlContext.xml.mssql with notepad, side by side.





2) copy your settings and replace the "New One". See below.




3) now rename sqlContext.xml to "sqlContext.xml.old", and rename sqlContext.xml.mssql to "sqlContext.xml"





4) restart service.
