I have found a very simple deployment script (will probably add more complex stuff in there as I get a little better at PowerShell/PowerCli, pretty new at this right now).
I would like to add some more functions.
1. I have multiple templates in vCenter (Windows 2019, Windows 2016 and Windows 2012). When I run the script I would like to being able to choose from the different templates. These templates will also use different VM Customization Specifications named in the same way as the templates. In this script I only use one template and one Customization Specification. How can I add this function to add more template (OS versions)?
This is how it looks right now (may a bit messy I know):
