I tried to upgrade my application from 6R2 cms to Episerver 7 but at initial stage popup is coming with connection string file format like
"The connectionStrings.config file for this site does not appear to match the EPiServer schema - could not find a matching <add> node"
Anyone has idea how to resolve this
Thanks in advance!
I would check what is mentioned in error message: verify what is in connectionStrings.config file (or where connection strings are defined in your case) on 6 R2 site.
