Generate a WSP package from existing SharePoint 2010 application

Question

I have a running SharePoint 2010 application running and I would like to extract the WSP so I can deploy that application in another server. I have no custom components yet so I'm not yet under Visual Studio. Is it possible to extract the WSP for the web app from central administration?

Many thanks

Answer 1

Yes it is possible to extract the wsp from the CA using the Power shell command.

Please take a look at this

To take single wsp backup use this

$farm = Get-SPFarm

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

$file.SaveAs(“c:\temp\JDSU.OneStop.wsp”)

To take multiple wsp backup use this powershell command

Start-Transcript "c:\wsp\transcript.txt"
[System.Reflection.Assembly]::LoadWithPartialName("Microsoft.SharePoint")

$solutions = [Microsoft.SharePoint.Administration.SPFarm]::Local.Solutions;
foreach ($solution in $solutions) {
$solution.SolutionFile.SaveAs("c:\wsp\" + $solution.Name);
}
Stop-Transcript

Hope this helps
