PAN_OS 10.0.0 upgrade issue

L1 Bithead

i am going to upgrade pan-os from 9.1.14-h4—>10.0.0–>10.0.11-h1–>10.1.0–>10.1.6-h6 for my pa 3260 device.But when the Pan-os upgraded to 10.0.0, i waited  for two hours and the global protect client can connect the portal and gateway, but it  can't access any network include Paloalto host ip, internal network and external network.  i accessed the device by internal netowrk. i didn't find any special log and it seem normal.   so i was not sure the issue and didn't continue to upgrade pan-os. At last i downgrade the pan-os to 9.1.14-h4,everything was ok.

    So i want to know if  pan-os 10.0.0 has this issue bug? can i continue to upgrade following   9.1.14-h4—>10.0.0–>10.0.11-h1–>10.1.0–>10.1.6-h6 ?

right now 9.1.14-h4, 10.1.6-h6 and 10.2.2-h2 are "preferred"
