We plan on upgrading our WCS from 188.8.131.52 to 184.108.40.206, to support the WLC's that run 5.2.178.
We know how to upgrade, but would like to know how to downgrade to a previous version in case we need to rollback.
The config guide only tells you how to upgrade:
It doesn't mention anything about downgrade / rollback procedure...
Take a backup of database on 220.127.116.11. In case you need to go back, uninstall the new version, then perform a clean install of 18.104.22.168 and restore the backup.
