JIRA Upgrade to 8.20.2

[Pradeep Naramaneni]

Hi, 

We have been running JIRA ok Kubernetes managed via Helm Charts. Currently, we are planning to Upgrade the JIRA version from 8.20.1 to 8.20.2. We just want to know what are the steps we need to do ?

Is it just update the Docker image name to latest and restart the deployment ?

@Pradeep Naramaneni it's better if you upgrade the entire Helm chart. See: Upgrades.

Technically, you can just update image in the stateful set, however, the latest Helm chart version may have some important bug fixes.

Please, do not use latest tag, it's always better to know what exact product version is pulled.

Yevhen, Thanks for the reply. I appreciate for your response.  Yeah we are planning to update helm chart also to 1.2.0. The steps we are planning to use

1. Scale down the Replicas to 1

2. Update Helm Chart to 1.2.0

3. Update JIRA Image to 8.2.0

4. Rollout the new Pods having new Image version

5. Re-indixing

6. Scale back the PODs/replicas to match before the Upgrade.

Couple of questions we have is 

1. Do we need to Put Jira into upgrade mode ?

2. Do we need to take a back up of any Plugins? (We have been using Clustered mode/Share-home directory)

3. Do we need to clean up local directory also before Upgrade? So new PODs will attach to new Disks instead of existing disks )

Pradeep, let me try answering your questions:

1. If you are using RollingUpgrade policy you need to enable ZDU mode

2. No it's not required. If you declared any additional plugins in values.yaml they will be persisted in the volumes

3. No, there's no need to clean up local home directory

Sure Thanks Yeven for you response.
