Some site found that the function of UTM upgrade online is invalid after testing guide the license and activating. it is invalid to upgrade online.
Look up license information by document tool, it finds that it not out of date.
License has been lead to sec.huaweisymantec.com successfully after the consultation. And get the activation code normally, download the UTM offline packets.
Check the license carefully, this license code is applied for ANY, not bound the ESN code of USG5320. verifying license for ESN code is unsuccessful when verifying online. This result in offline.
Apply the appointed ESN code license again, the failure recovered.
