Import Device configuration into Panorama, Device window is blank

[PaulTowns]

Trying to import HA pair into Panorama, follow the docs on importing configuration into panorama (Migrate a Firewall to Panorama Management (paloaltonetworks.com)) Follow steps 1 -3 and all fine at step 4 where it says '

"From Panorama, select Panorama >Setup>Operations, click Import device configuration to Panorama, and select the 

Device."

I have no device  

Under managed Devices > Summary,  the PA3250 I want have Panorama managing are there and show as connected

Hello @PaulTowns

Could you try to restart management process on Firewall side?

Could you make sure that Firewall is not assigned to any existing Device Group?

Kind Regards
