After the Version Is Upgraded, Do I Need to Apply for a License Again?
After the version is upgraded, apply for a license according to activated licenses before the upgrade and license support before and after the upgrade.
After the upgrade, run the display license command to check activated licenses. The Product version field indicates the license version number.
If V200R001 is used, only the PBX function is controlled by the license.
If V200R002 or later is used, voice service (SIP AG), data services, security services, CM&BEST, CT, and IVR are controlled by the license.
Then check license support before and after the upgrade. There are license differences between different versions. Table 1 describes mapping between product versions and supported licenses.

Apply for a license according to activated licenses before the upgrade and license support before and after the upgrade.
If a license has been activated before the upgrade and the licenses for required functions have been activated after the upgrade, you do not need to apply for a license.
If some functions are added after the upgrade, apply for a license for the new functions. For example, if WLAN AC Express is added after the device is upgraded from V200R002C00SPC200 to V200R003C00, apply for a license for WLAN AC Express.
