I'm creating a new site template that I will need to move from my development to production server. I have saved the template as a .wsp file and installed it on my staging server without any problems. However, I know once the site goes into production
that changes will occur and I will need to upgrade the site template.
I have tried to make changes to my development site and save a new site template, and then move to my staging server and upgrade the existing solution using the below PowerShell command, but I get an error that the GUIDS are different and
the solution cannot be upgraded.
Command: Update-SPUserSolution -Identity MyTemplate v1.wsp -Site
http://webapplication/site -ToSolution MyTemplate v2.wsp
Error: Update-SPUserSolution : Given solution cannot be upgraded to the provided ToSolution because the solutions have different Guids.
Does anyone know how I would upgrade the solution when using a site template as the bases for the solution?
