This is just a quick post that is more for personal reference more than anything.

I needed to move my original test design around a bit and this involved installing new highly available DEM Ochestrators and removing the old one.
Uninstalling the old DEM Orchestrator instance wasn’t a problem, however, I noticed that it was still listed in
Distributed Execution Status as offline.
Here are the steps that I took to fully remove the old DEM Orchestrator from my environment:
- Snapshot, snapshot, snapshot!
- Install the two new DEM Orchestrator instances
- Uninstall the old DEM Orchestrator instance
- Back up your IAAS database!
- Remove the old DEM Orchestrator entry from the IAAS database
Step 5 Explanation
First double check that the entry for the old instance is present:
use vCAC SELECT * FROM [DynamicOps.RepositoryModel].DEMs go
You should see the old DEM Orchestrator instance in the list. Remove it with the following TSQL statement:
use vCAC DELETE FROM [DynamicOps.RepositoryModel].DEMs WHERE FriendlyName = 'OLD-DEM-ORCHESTRATOR' go
Now restart the IAAS services and take a look back in Distributed Execution Status. The entry should now be gone.
