Upgrading Qubes 4.1 to Fedora-33 difficulty

[estoner]

I can not switch sys-firewall & sys-usb to fedora-33-dvm.
I was able to switch all my other Qubes successfully.
sys-firewall & sys-usb are setup as disposable using fedora-32-dvm.
I successfully created and tested fedora-33-dvm.
I can shut down sys-firewall & sys-usb but I still get an error message when I try to switch templates.
My system runs fine with sys-firewall & sys-usb on fedora-32-dvm but I would like to fully transition to fedora-33.

I have read, and reread the docs on switching template versions but can not find the solution.

Can anyone assist me with a procedure. Or point me in the right direction.

Currently you can’t change the DVM template of a static disposable VM, you have delete and recreate the static disposable VM. (It’s not that bad since there’s no data in them).

Edit: Well, it’s like that in 4.0. Not sure about 4.1.

Run into this with fedora-35 upgrade and for those who are still looking, go here

Switching to new Fedora

So upgraded fedora and I have switched everything that needed to. How do I switch my “sys-usb” as soon as I stop it so I can switch it I have no usb mouse? Is there some cmd to run in dom0 I can do to switch sys-usb to new fedora? Also in qubes manager on the far right the column states “default disposable vm” for everything which stills has to old fedora. How do I switch that so it states the right fedora I am using??? thanks
