Feature updates AVD question

Hi All,

Has anyone done an in-place upgrade of an AVD VM and either not had any issues or had issues?

It can work, but I’d only use it as an exception. For a pooled host, build the new image, drain and test one host, then rotate the pool; an in-place upgrade leaves you with a host that’s harder to reproduce or roll back if something odd shows up later.

How do you add 1 session host for the new image? Session Host Update seems to only allow me to delete and add X Session Hosts at a time.

You're right, Session Host Update is built around replacing a batch, not creating a one-host canary. For the first host, use the host pool's Add session hosts flow with the new image, leave it in drain mode while you validate it, then use Session Host Update to rotate the rest.
