Migration Steps from Version 3.4.x to 3.5.0

Follow these steps to upgrade Pulse.

Update Configuration:
- Update ImageTag in the $AcceloHome/config/accelo.yml file to 3.5.0.
Push Updated Configuration to Database:
- Run the following command:

Bash
    
 
accelo admin database push-config

Run Migration Command:

Make sure you run the command from $AcceloHome.
Do not change the value of -v from 3.5.0 unless explicitly advised by Engineering. The following command needs to run on all Pulse nodes including standalone nodes i.e. nodes where PULSE_SA_NODE is true. Examples of such nodes include but aren’t limited to Logsearch, FS Analytics V2, Dashplot .

-v: This indicates the version you are migrating to.
-i: This indicates the version you are migrating from. For example, to migrate from 3.4.1 to 3.5.0, make sure to run the following command from $AcceloHome.

For Single Cluster:

Bash
    
 
accelo migrate -v 3.5.0 -i 3.4.1 -b
Copy

For Multi-Cluster:

Bash
    
 
accelo migrate -v 3.5.0 -i 3.4.1 -a -b

- If the above is present, change the port number from 19013 to 19051.

Bash
    
 
yarn_app_es_urls: <http://<LOG_SEARCH_HOSTNAME>>:19051
Copy

Reconfigure Cluster:
- To get the updated configuration for agents, run:

Bash
    
 
accelo reconfig cluster -a
Copy

Push Updated Configuration to Database:

- Finally, run the following command.

If readOnlyRootFSEnabled is set to true in $AcceloHome/config/accelo.yml, then follow the steps listed below instead of running the command directly.

1 . Open $AcceloHome/config/accelo.yml and set the value of readOnlyRootFSEnabled to false.

Run accelo admin database push-config
Run accelo restart all -d.
Run accelo admin database index-db.
Open $AcceloHome/config/accelo.yml and set the value of readOnlyRootFSEnabled to true.
Run accelo admin database push-config.
