Migration Steps from Version 3.7.x to 3.8.0

Follow these steps to upgrade Pulse.

Take a backup of the accelo file and download the latest version for accelo.linux CLI.
Move and make the latestaccelo CLI file as an executable. Also, check the updated Pulse information for the following:

Bash
    
xxxxxxxxxx
 
mv accelo.linux accelochmod +x ./accelo
Copy

For the Offline Installations, download all the latest image packs and run the following command to upload the latest images.

Bash
    
xxxxxxxxxx
 
docker load -i
Copy

Push the updated configuration to the database.
- Run the following command:

Bash
    
xxxxxxxxxx
 
accelo admin database push-config
Copy

Follow the manual steps in the document below to update MongoDB to the latest version, 8.0.8.

For information about migrating MongoDB manually, see Upgrade MongoDB Manually.

Update Configuration:
- Update ImageTag in the $AcceloHome/config/accelo.yml file to 3.8.0.
For the Online installations, run the following command and press 'Y' at the prompt to get the most recent binaries.

Bash
    
xxxxxxxxxx
 
accelo login dockeraccelo pull all
Copy

Run the command below to update and add new keys in vars.yml

Bash
    
xxxxxxxxxx
 
accelo reconfig cluster
Copy

If your ODP cluster has Kafka 3 installed, run accelo config cluster before performing this step.

[Optional: If AD-LDAP is deployed] Run the following command to generate an encrypted password for the LDAP server connection.

Bash
    
xxxxxxxxxx
 
accelo admin encrypt
Copy

Enter the plain-text password to generate the encrypted password.
Update the bindPW field in /data01/acceldata/config/ldap/ldap.conf with the encrypted value and add the encryptedPassword = true flag in the same configuration file.

Run the below command to push acceldata.conf and other updated files to MongoDB.

Bash
    
xxxxxxxxxx
 
accelo admin database push-config
Copy

Once the above command is executed, move the license from local work directory to a backup directory.

Ensure that you do not change the value of v from 3.7.0 to anything else unless explicitly advised by Acceldata. The following command needs to run on all the Pulse nodes including standalone nodes i.e. nodes where PULSE_SA_NODE is true. The examples of such nodes include, but aren’t limited to Logsearch, FS Analytics V2, and Dashplot.

Run the migration command. For example:
1. -v 3.8.0 : The version you are migrating to.
2. -i 3.7.0 : The version you are migrating from.
3. To migrate from version 3.7.0 to 3.8.0, the migration command looks as shown below.

Ensure that you run the following command from $AcceloHome.

For a single cluster:

Bash
    
xxxxxxxxxx
 
accelo migrate -v 3.8.0 -i 3.7.0 -b
Copy

For multi-cluster:

Bash
    
xxxxxxxxxx
 
accelo migrate -v 3.8.0 -i 3.7.0 -a -b
Copy

Run the same command again, If any issue occurs during migration on any step.
Restart all the containers so that they use the updated images

Bash
    
xxxxxxxxxx
 
accelo restart all -d
Copy

Uninstall the Hydra Agent.

Bash
    
xxxxxxxxxx
 
accelo uninstall remote
Copy

Install the Hydra Agent.

Bash
    
xxxxxxxxxx
 
accelo deploy hydra
Copy

Reconfigure the cluster to get the updated configuration for Agents.

Bash
    
xxxxxxxxxx
 
accelo reconfig cluster -a
Copy

To push the updated configuration to the database, execute the following command.

Bash
    
xxxxxxxxxx
 
accelo admin database push-config -a
Copy

To configure when gauntlet snap must run the MongoDB cleanup and compaction, run the following command.

Bash
    
xxxxxxxxxx
 
accelo config retention
Copy

Finally execute the following command to create indices for database collections.

Bash
    
​x
 
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.2. Run accelo admin database push-config 3. Run accelo restart all -d.4. Run accelo admin database index-db.5. Open $AcceloHome/config/accelo.yml and set the value of readOnlyRootFSEnabled to true.6. Run accelo admin database push-config.7. Run accelo restart all -d.
Copy

Bash
    
xxxxxxxxxx

Copy

If the older playbooks already present in the node where ad-director is deployed, delete them, and download the latest playbooks tar from the License UI.
1. Delete the older playbooks using the command: rm -rf $AcceloHome/work/<cluster_name>/director/playbook/*.Replace <cluster_name> with name of the cluster where the playbooks are present.
2. Download the playbooks tar from the License UI. For details, see Deploy Playbooks.
