Taking Backup of Deployed WSP in SharePoint 2010

To take the backup of the WSP in SharePoint 2010,

Run the following commands from Powershell where SharePoint 2010 is configured.

Add-PSSnapin Microsoft.SharePoint.PowerShell

$farm = Get-SPFarm

$file = $farm.Solutions.Item(“mysolution.wsp”).SolutionFile

$file.SaveAs(“C:\WSPs\mysolution.wsp”)

This saves the wsp to the desired location. The WSP can then be deployed like any other solution.
