F5-BIQ-VE-S Software upgrade

No issue encounter so far in BIGIQ 5.2.0. I will recommend below points before upgrading. Its helps me a lot.

1) Generate UCS of both pair & save in laptop/remote location.

2) Generate qkview of both unit & save to laptop/remote location before upgrade, in case support team require to check any thing.

3) Re-activate the BIG-IQ system license. You must do this on both the active and the standby BIG-IQ if they are running in an HA pair.
