I have a Sharepoint solution installed. I want to install a newer version of the solution as an upgade which I did using :
Update-SPSolution –Identity MySolutionName.wsp –LiteralPath “C:\MySolutionName.wsp” -GACDeployment
This command seem to work fine as there are no errors however after I run this, the whole solution becomes uninstalled. Does anyone have any ideas on why this could be or point out where I am going wrong?
