Summary : Deploy WSP Solutions to 14 and 15 Hive with Install-SPSolution SharePoint 2013,Using CompatabilityLevel to Install WSP Solutions in 14 and 15 Hive,Install SharePoint 2010 solutions in SharePoint 2013 site collections.
In SharePoint 2013 with the new “CompatabilityLevel” parameter of Install-SPSolution cmdlet you can now Deploy your wsp Solutions to 14 hive, 15 hive or both. The default behavior, if this parameter is not specified is to install the solution only to the version directory based on the version tracked in the manifest of the solution’s cab file.
The Install-SPSolution cmdlet only deploys an installed SharePoint solution in the farm. You use the Add-SPSolution cmdlet to install a SharePoint solution package in the farm.
The following table lists the valid values for the CompatabilityLevel parameter:
|14||Installs solution to 14 directories only|
|15||Installs solution to 15 directories only|
|“14,15”||Installs solution to both 14 and 15 directories|
|“AllVersions” or “All”||Installs solution to both 14 and 15 directories|
|“OldVersions” or “Old”||Installs solution to 14 directories only|
|“NewVersion” or “New”||Installs solution to 15 directories only|
