Upgrading a Cell Environment

Note: This procedure has changed since 1.0.12.0. In previous versions the process of upgrading a cell environment was different.

To upgrade a cellenvironment:

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

2. In the cell manager, execute the following command:

   Code Block
   curl -X PUT "montier-es-http:9200/_cluster/settings" -H 'Content-Type: application/json' -d'{"persistent":{"cluster.max_shards_per_node":"20000"}}' Expected response: {"acknowledged":true,"persistent":{"cluster":{"max_shards_per_node":"20000"}},"transient":{}}

3. Upgrade the cell manager.

4. When the cell manager upgrade is complete, only the following services should be up and running - MonTier-AppAdmin, 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.

5. Copy /app/keys directory (including any sub-directories) from the cell manager to all cell members (this will share the encryption key and generated certificates between the cell components).

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

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