Restore site collection from prod to dev fails with version mismatch

I am attempting to move a prod site collection to dev.  I made a backup of the prod site collection and attempt to restore it to dev using PowerShell:

Restore-SPSite -Identity "http://servername" -Path "\\server\spbackups\inranetbackup" -Verbose -Force

I am getting the error:

"Your backup is from a different version of Microsoft SharePoint Foundation and cannot be restored to a server running the current version.  The backup file should be restored to a server with the version '4.1.23.0' or later"

I have validated the versions between prod and dev for SharePoint Fundation services and they are identical.  I insured that the same service pack and hotfixes are installed.  I also noted that the majrity version numbers are 14.0.6029.1000 and not 4.1.23.0.

Any help or suggestions would be greatly appreciated.
