Citrix WEM On-Prem Upgrade 4.5 to 1811 “This can be used as guidance up to 1912”

Great blogs

Infrastructure Services

1. Run the installer of the Infrastructure Services version you want to upgrade to. 
   1. This may not be needed, but I do it as a safety net.
2. You should manually stop the Norskale Infrastructure Services service before upgrading to ensure the upgrade is successful.

I just do the basic install, I use to tell it to install the Cache on the D drive. But that’s really not needed anymore. I use BISF, and tell it to move it for me. I like to have a D drive on my machines (PVS).

Reference

Citrix WEM Updated Start-Up Scripts

James Kindon, has done the work for you, Use his scripts.

The following changes are going to occur so be ready:

• The new process name is: Wem.Agent.Service.exe 
• The new path structure is: %ProgramFiles%\Citrix\Workspace Environment Management Agent

1. An upgraded installation of the WEM agent will result in partial changes to your environment:

• The new process name is: Wem.Agent.Service.exe 
• The path on the file system will not be altered and will remain as it was: %ProgramFiles%\Norskale\Norskale Agent Host

Be aware also that in both clean and upgraded deployments, the Windows Event logs will change from Norskale Agent Service to WEM Agent Service

	Old (Pre Cloud Service 1903 and On-Prem 1909)	New (Post Cloud Service 1903 and On-Prem 1909)
Installation path	%ProgramFiles%\Norskale\Norskale Agent Host	%ProgramFiles%\Citrix\Workspace Environment Management Agent

*One thing to note on Port*

Cache synchronization port. (Applicable to Workspace Environment Management 1909 and earlier; replaced by Cached data synchronization port in Workspace Environment Management 1912 and later.) The port on which the agent cache synchronization process connects to the infrastructure service to synchronize the agent cache with the infrastructure server. The cache synchronization port must be the same as the port you configured for the cache synchronization port (WEM Infrastructure Service Configuration > Network Settings) during the infrastructure services configuration. The port defaults to 8285 and corresponds to the AgentCacheSyncPort command-line argument.

Alternatively, you can specify the port using a command-line option in the silent installation of the WEM agent
