Microsoft released Technical Preview 2105 last week and with it came some CMG changes, one of which is the ability to decide the size of the CMG VM while creating the CMG. I covered that process in this blog post. But you also can now change the size of an already deployed VMSS (Virtual machine scale set) CMG and I’ll cover that in this post.
Let’s imagine I’ve created a Lab (B2S) CMG.
Verify current settings
You can verify the current VM size settings in at least two places. In ConfigMgr, check the CMG properties, then select the Settings tab to see what size it’s configured to.
To change the VM Size simply click the drop down menu beside VM size in the CMG settings and change it to the setting you wish to move to and then click Apply.
This will be reflected in the CloudMgr.log
In the ConfigMgr console, the CMG should be listed with a status of Ready.
Finally, in Azure, you’ll see the changes are applied.
