The capabilities of PowerShell/PowerCLI always intrigue me; when I'm tasked with any project or objective where its usage saves time, increases consistency and makes work more efficient, I look for methods to integrate it. Not being exceptionally proficient with it requires me to often research and test, but it's well worth it when the results achieve the target goal consistently and productivity improves.
I was once involved in repetitive, planned Disaster Recovery Tests (Bubble Tests) that had a very specific requirement: The failed over VMs in the isolated network needed to have IP settings that varied from the settings of their SRM Recovery Plans. Changing the actual Recovery Plan settings for each one of the involved VMs and groups was not allowed - If there was ever a need for a true fail over event and the Recovery Plan was modified, that would not have been good, plus that would mean changing the entries back after the tests completed.

Initially the IP, Default Gateway and DNS values for the VMs in the 'Bubble' were manually changed from the console; this method consumed a lot of time as we needed to do it for multiple machines, it was prone to errors and had to be done every time the Bubble Tests were ran.
Invoke-VMScript cmdlet, is an amazing tool!
The goal was to change IP, Subnet, Default Gateway and DNS values. Since the bubble tests were repeated, it was worth taking the time to build the commands for each VM.
