Does updating appstack auto unmount the old appstack on the next login or reboot and attach the updated appstack

I didn't see this behavior where in updated appstack auto attaching and detaching . is it so ?

Can updates be performed to an AppStack without disrupting users who have the AppStack in use?

A. Yes. You update applications on the original AppStack from the App Volumes Manager console. This process

clones the original AppStack, so the existing applications are available to users. The new AppStack with the

updated applications is provisioned at next login. Also, the old AppStack is deprovisioned the next time the

user logs in.
