It's purpose is to be set up quickly and destroyed after you are done with your development or test. Devstack can't even be rebooted out of the box; I can't imagine that there is a procedure to upgrade Devstack.

Yes, there is no upgrade procedure for DevStack. And yes, it is intended to be used for OpenStack testing as mentioned in
doc also.

I am not 100% sure about your usage of DevStack for developers if that is for their development env for any other software or
OpenStack dev/testing. But in any case, If you want to move to the latest version of DevStack, the best way is to clone the latest
(or specific release) source code and install it as fresh. If you try to update the existing devstack to the latest release code and run ./stach.sh
again, it is no guarantee that it will work.

If you want to create the permanent dev env for the developer, I will suggest you try some other deployment project like Kolla, OSA etc.
