The Revert Software application simultaneously reverts both the Active (WFDSBC01a) and Standby (WFDSBC01b) server. On continuing with the revert, the upgraded server(s) will reboot and come up with an earlier release. During this process browser session will be lost and need to re-login.
The Revert Software starts and changes the boot version to earlier version in both the active and standby server. For example, in this case, it is 04.02.03R000 version. You can see the revert status in the Log section.
Once you see Rebooting message in the logs, log out from the EMA.

Verify the revert software versions in Platform > Software Versions.
