Known Affected Releases

12.0(1.24900.7) 12.5(1.22900.7)

Description (partial)

"Post-upgrade Tasks" section is missing a mandatory step to manually update the CTL file after the upgrade if the cluster is in mixed mode. This should be clearly stated in this section due to the fact that the ITLRecovery certificate is re-generated automatically to increase its validity and create one ITLRecovery certificate per cluster.

The only mention about this fact is inside of Pre-upgrade Tasks > section Regenerate a Certificate:

During an upgrade, the ITLRecovery certificate is generated per cluster. If the cluster is in mixed mode, manually update the CTL file. Reset the phones to reflect the latest updates.

Affected sections:


Upgrade to UCM 12.x and later
