Hi all ConfigMgr enthusiasts!
As ConfigMgr new TP rolls out monthly you may want to automate this upgrade process. As always, PowerShell is your firend. With TP1709 I wrote a small script that you can use to semi-automate your upgrade process. With a bit of further developement you can turn this script to update function and schedule it - voilà a fully automated TP upgrade process!
Currently the script checks for new TP update, initiates download, runs prerequisite checks and installs the update. You will have to run this script line-by-line and check for the results before continuing.
Script also grabs some PowerShell cmdlet info from currenty installed version and saves it to a JSON file. After upgrade you can run the info gathering part again and compare JSON files to see what has changed between TP's.
As always, please send comment through Twitter @arisaastamoinen
