Removing/uninstalling a Site Server requires the following steps:
Note:
Removing/uninstalling / decommissioning a Site Server implies that any client machine registering to it will need to register to a new one. This process is automatic after the Site Server has been removed: When the client machine can't reach the Site Server (if these client machines are set to be "manually assigned" (Managing Manually Assigned Agents) to a Site Server, then these client machines will keep retrying the same Site Server until that assignment is removed), the client will request a new assignment based on the available list of Site Servers.
As well, if this Site Server has the Package Service installed, any package or image file, will be deleted. Make sure other Site Servers have those packages/files available.
