Citrix VDA upgrade from 1912 to 2203 using scripts and GPO (no SCCM required).
Steps:
1. Move VDAs to OU with uninstall script
2. Unlink uninstall GPO and link GPO to clean-up task scheduler
3. Move VDA to OU with GPO to install new VDA 2203
4. Move all VDAs back to their OU
You can do all this in the same Organization Unit if you don't have permissions to move objects. Just link and unlink GPOs or schedule all in the task scheduler and go to sleep (living on the edge).
