Upgrading a Cell Environment

To upgrade a cellenvironment:

1. Make sure the entire cell is up and running. Upgrading is possible only if the cell is healthy.

2. Upgrade the cell manager.
   When the cell manager upgrade is complete, only the following services should be up and running - MonTier-Derby, MonTier-es-raw-trans-Node-1/2/3/4 (the Web Console will be unavailable).
   Do not start the other services manually on the cell manager unless requested explicitly.

3. Upgrade all cell members (can be done in parallel).

4. When the cell members upgrade is complete, start the cell manager services using the app-util.sh ("Start All").

Backup the Servers

It is highly recommended to perform a full backup (including the operating system) of all DPOD servers prior to upgrading, so the system can be restored in case of a failed upgrade.
