In this article, I’ll show you how to upgrade the latest WSP file to an existing file on Farm Solution in a few simple clicks.

You can save the WSP file in any folder.

Open SharePoint PowerShell and run it as administrator; then run the following script:

Install-SPSolution -Identity <File Name> -WebApplication <URL>
-GACDeployment 

For example:

Update-SPSolution
-Identity Bamboo.CalendarPlus.wsp
-LiteralPath “C:UsersspinstallerDesktopHW20.R4.7.SP2016.SLBamboo.CalendarPlus.wspcabBamboo.CalendarPlus.wsp”
-GACDeployment 

Give it a moment, then go to Central Admin->System Settings->Manage Form Solutions.

We can see the Bamboo.CalendarPlus.wsp file upgraded on it.
