Solution deployment is one important task
for SharePoint developer/admin, being it in local environment or any other
Production/non-production farm.
Here is a script
to automate this job and avoid errors. Only manual task here is to provide
“Variable Values”, i.e. – name of WSP, path, web application URL etc.
In this
case WSP is already added to farm solution store and deployed. We did some
changes in existing code and need to update the solution. The Update-SPSolution
cmdlet upgrades a deployed SharePoint solution in the farm. Use this cmdlet
only if a new solution contains the same set of files and features as the
deployed solution. If files and features are different, the solution must be
retracted and redeployed.
1.
Copy the script below, save it as PS file, i.e.
– UpdateSolution.ps1
2.
Edit it in any compatible editor; change Declaration
of the Variables section
as per your requirement.
3.
Open PS prompt/SharePoint management Shell with
admin rights.
4.
Navigate to the folder where PS file is saved
5.
Execute the PS file as .\UpdateSolution.ps1
