I can not delete old Device Pool

[Sergey 1907]

I have misunderstandings. I made a new Device Pool and moved there all the devices that were tied to the old Device Pool. But I cannot delete the old Device Pool, since in the dependencies I see 31 devices that are tied to it in the Device - Device Settings - Device defaults. But in the Device Defaults all devices belong to the new pool. How to find these invisible devices and change their device pool?

It might just be me, but where did you get the pkid for this part?

From the first query you get two pkids and then you use a completely different one in the next query. I don't follow that part. Would you mind to elaborate?

Moment! I will restore the previous version from the backup. Minutes 30
