When upgrading to newer versions of PSAppDeploy, do we need to replace the Deploy-Application script, or can we just replace everything else?
Depends on how much of a jump you are doing.
If you are upgrading from 1.8.x, at some point
Execute-Process got a change in behavior when it got the new
You should be okay going from 1.8.4 to 1.9.3.
Regardless, I do not recommend changing the
\AppDeployToolkit\ folder on perfectly good packages without testing.
I only “Upgrade” when I need to update the application.
Otherwise it’s a make work project and you risk getting surprises.
