Upgrading Norskale VUEM to Citrix Workspace Environment Management
I was working with a customer that was an original Norskale customer. They were running VUEM 3.1 I started the process of upgrading to Citrix Workspace Environment Management (WEM). I upgraded all the components and it seemed to have no issues. I started trying to connect the clients and weird issues started to appear. The client would keep saying unable to connect to the broker environment. The logs showed errors regarding the VUEM Agent Monitor Sync is erroring. When running the AgentCacheUitlity, it would produce an error regarding VUEM Agent Monitor Cache failed. The cache would show that things were being downloaded and the agent performance optimizations would still apply and work.
The brokers were giving no indication of any errors. After further analysis, it looks like the DB is not fully upgraded. I restored the DB to the 3.1 version and began the upgrade process again. This time I started by upgrading to 3.5.2 first, then testing. After upgrading to 3.5.2, I tested the client after reinstalling the 3.5.2 client. Everything is working at this point. At this point, I upgraded to 4.0.2 and had no issues.
What I have learned from this exercise is that the DB needs to be at the schema level for 3.5.2 before upgrading to the Citrix version of WEM.
