Upgrading to Jenkins LTS 2.32.x

[Makarand Jadhav]

Hi,

We are planning to upgrade Jenkins from ver. 1.640 to LTS 2.32.1. I checked the upgrade guides listed on https://jenkins.io/doc/upgrade-guide/2.32/#upgrading-to-jenkins-lts-2-32-1 but it does not seem to give direct information on the upgrade requirements from server resources & software's perspective. Our plan is to perform Jenkins upgrade on our Dev infrastructure by scaling up the dev infrastructure to match up the Production server Infra first. So I have few queries on server resourcing requirements for upgrade to happen:

1. Jenkins server requirement for upgraded Jenkins server version(ie memory, cpu, etc.)?
2. List of compatible software/s with Jenkins LTS 2.32.1, I can see that Jenkins 2.32.1 upgrade guide lists that Java/JDK 7 might be needed?

Or,
Are the instructions listed in https://jenkins.io/doc/book/getting-started/installing/ & https://jenkins.io/doc/book/hardware-recommendations/ suffice for the upgrade process as well?

Thanks,

Makarand

Jenkins has no substantially different hardware and platform requirements between 1.640 and 2.32.x, with the exception of what's listed for 2.7.1:

https://jenkins.io/doc/upgrade-guide/2.7/#upgrading-to-jenkins-lts-2-7-1

In general, you should read all upgrade guides for intermediate versions, as they're written with a upgrade from the previous LTS release in mind, and you're skipping quite a few. Unfortunately we only started doing that with 2.7.1, so the jump from 2.40 to 1.651.3 has no specific documentation other than the changelog.
