I am in a new role supporting Horizon with App Volumes (2.14) after spending about 6 years with Horizon but only a standard license. I replaced the VDI person so I'm trying to figure out how things are setup as well as make changes to improve things. I think I understand the basics with App Volumes, but hope someone can help with a question.
Background: We have 2 VDI Datacenters: USA East Coast and USA West Coast using instant clones. Users are directed to one DC or the other based on their office location (different connection strings, not Global Load Balance). Each DC has it's own golden image and two App Volume Manager servers (as well as connection brokers, UEM server etc.). The golden images have their registry updated to reflect Manager2 in addition to the preconfigured Manager1. This works as expected.
I was told that the west golden image had some changes to it that the east golden image had not had yet so rather than try to figure out what those were (patches? apps installed? driver changes?) I followed this blog post Managing Horizon Gold Images Across Multi-Site Deployments - VMware Blogs to effectively copy the golden image from west to east. I then powered it up in the east DC, changed the Manager1 and Manager2 IPs (I actually exported that registry section (HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\services\svservice\Parameters) from the west golden image and imported it in the east golden image), shut down the golden image, took a snapshot, and created a test pool matching the settings of the current live pool including putting the machines in the same OU etc but only made 10 machines instead of the 1800 in production.
After the machines were ready, I connected in and none of the apps are on the desktop. So apparently there is more to the app volume agent install than the service running and relying on the registry to point to the manager.
So my question: What is the best way to handle this if I want to update just 1 golden image and then copy it to the other DC and use it there? Can I just uninstall the App Volumes Agent and reinstall it on that copy of the golden image? Is there some other change besides just the registry hive?
Thanks in advance for any help with this.
