To keep the Data Domain storage healthy maintaining both performance and security at highest levels, the upgrade of the OS should be done on regular basis.
The upgrade should be done when the load on the storage is minor to avoid performance issues.
Check the upgrade path
Before proceeding with the upgrade of your Data Domain, it is necessary to verify the current installed OS version and the desired upgrade version to verify the correct upgrade path.
In this example, the OS 22.214.171.124 version is installed in the Data Domain to upgrade. From Dell-EMC website latest available OS version is currently the 126.96.36.199.
Reading the controller upgrade notes it is reported:
All controller upgrade eligible systems (head swap) to DD9900, DD9400, DD6900, must upgrade to DD OS 188.8.131.52 prior to performing the controller upgrade.
A direct upgrade from version 184.108.40.206 to 220.127.116.11 is then not supported but it is necessary to upgrade to version 18.104.22.168 first.
