To resolve this issue, please install a PSA-V core license.
After a core license is installed, the platform model remains as "
VMware-VA-SPE" instead of "
PSA5000-V", until the virtual appliance is upgraded to 9.0Rx, please see below examples:
Example:
Platform > Model status of 8.3R3:
Platform > Model status after 9.0R3.1 upgrade:

Note:
- Upgrading a VA to 9.0 could take a long time to complete so please monitor the serial console. It takes a while to encrypt the disk and then finally doing post installation, recreating data partition, extracting runtime contents of the package, creating link to 64-bit binaries, initializing RNG, and then starting the new 9.0Rx system. It is followed by importing various files and data.
