Post-Upgrade step for ISE version 2.4

[ngubanov]

Hi experts!
There is a Post-Upgrade step for ISE version 2.4 in the documentation:
"With the operational data backup of MnT data that you created before update, restore the backup.
Failing to perform backup and restore could trigger a High RADIUS Disk Usage Alarm.
The maximum size for an MnT database file does not get updated correctly while upgrading, and the database file fills up."

Is there real need to restore the backup after the upgrade is done if upgrade is completed successfully?

BR, Nikolay.

yes to avoid the risk of having this alarm. I did upgrade without facing
this issue but restored the backup to avoid risks.

That's not something I have ever done and I have never had an issue. I believe this could be a carry over of documentation steps from earlier releases, but Cisco has since fixed the issue.
