<p class="MsoNormal"><span style="color:#1F497D">The rollback option requires all phones to be reset after changing the Enterprise Parameter so that the phones can get the new blank ITL. After they get the new blank ITL is when you can then move it to the
other cluster. The rollback option isn’t preferred since phones on the old cluster will have problems with secure services such as corporate directory before they are moved to the new cluster. I’d suggest using the Bulk Certificate Export/Consolidate/Import
option to maintain 100% functionality while also allowing you to roll phones back to the old cluster if something went wrong with the upgrade easily. Check out
