Hi @DevOps1 ,

 

The maximum supported version is 11.1.  https://docs.paloaltonetworks.com/compatibility-matrix/supported-os-releases-by-model/palo-alto-netw...

 

The current recommended release for 11.1 is 11.1.4-h1.  https://live.paloaltonetworks.com/t5/customer-resources/support-pan-os-software-release-guidance/ta-...

 

From my experience, I have seen newer versions of PAN-OS cause GUI slowness, but the performance has always been good.

 

Thanks,

 

Tom
