What is the best way to completely remove a WSP from SharePoint? SO when you reinstall it again from scatch it thinks it is a clean install?
1 Answer
We can either manually do it through central admin or by using powershell commands.
I would prefer doing this through powershell
To uninstall and remove Farm solutions use the Uninstall-SPSolution and Remove-SPSolution cmdlets (Use -WebApplication attribute if the solution has webapplication-scoped resources):
Uninstall-SPSolution –Identity MySharePointSolution.wsp –WebApplication http://webapplication
Remove-SPSolution –Identity MySharePointSolution.wsp
To uninstall and remove Sandbox solutions use the Uninstall-SPUserSolution and Remove-SPUserSolution cmdlets:
Uninstall-SPUserSolution –Identity MySharePointSolution.wsp –Site http://webapplication/sitecollection
Remove-SPUserSolution –Identity MySharePointSolution.wsp –Site http://webapplication/sitecollection

2Remember that any artifacts that were added to the Content DB (for example .webpart files in de Web Part Gallery) will still exist after the WSP is completely removed from the farm. Commented Jan 31, 2012 at 13:53
