SharePoint Farm Feature

Question

I want to install .wsp but it gives an error saying that there is a farm feature in which need to be removed. how to Remove Farm Feature (Farm Level Feature) from Central Admin or trough Power-Shell ?

Answer 1

It might be because there is already a solution with the same name (i.e. it is already installed)

From PowerShell with the SharePoint snapin loaded, first run:

Get-SPSolution

This will list all the installed solutions. Look for the solution that has a matching name and verify that it is listed.

If you want to remove the existing solution, run the following:

Remove-SPSolution -Identity the_solution.wsp

Answer 2

The issue was though i remove the SPSolution some farm level features remain there. in my case the BDC model i created for my external content type. how i get it sorted was i add SPSolution and installed it with -Force and then uninstalled it and removed the solution. other than that there is no specific was to remove only the farm feature as i found. i had to remove the whole solution.
