RHEL 6.10 to Ubuntu 22 Migration

[do_Ob]

Hello cPanel Gurus,

We are moving out of RHEL to Ubuntu 22. Currently we have the following cPanel instances

RHEL 6.10 vmware [Node1] v86.0.40
RHEL 6.10 vmware [Node2] v84.0.21

I've been reading guides and whatnot about migration and initial setups but I couldn't find a clearcut approach on how to achieve our goal - Migrate our existing cPanel instances running on RHEL (6.10) to Ubuntu 22.

How to Move All cPanel Accounts from One Server to Another | cPanel & WHM Documentation

This tutorial explains how to migrate your cPanel accounts, SSL certificates, and main server IP address from one server to another. Typically, you would do this when you need to replace your server.

docs.cpanel.net

The steps are straight forward, but is not valid on what we currently have.

Initially I had this in mind for implementation.

1. Upgrade cPanel to the latest version which is v108 on the RHEL boxes.
2. Build the new Ubuntu 22 systems and install v108 on them.
2. Follow the How to Move All cPanel Accounts from One Server to Another
3. Problem solved.

But as painful as it is, I'm already stuck and destroyed just on step 1, because RHEL 6.10 EOL'd so long ago.

Another option I had is -

1. Build the new Ubuntu 22 systems and install the same versions (v86.0.40 and v84.0.21) accordingly
-> going to Secure Downloads | cPanel, Inc. only has the latest release, is this even possible? Install an old version?
2. Use the transfer tool and transfer the production site(s) from RHEL to Ubuntu
3. Upgrade cPanel
4. Problem solved.

Then again, I'm not even sure if the install of older version is allowed.

Reaching out to the cPanel gurus out there for suggestions on whats the best course of action to complete the migration.

Hey there! Unfortunately, none of that plan is going to work properly. You wouldn't be able to install a cPanel server with anything older than version 106 at this time, and cPanel only supports Ubuntu 20.04 right now as we don't have version 22 support ready.

You'll want to do the following:

-Create a server with Ubuntu 20.04
-Install cPanel
-Use the Transfer Tool to move the sites to the Ubuntu machine

Appreciate the response!

Do I need to apply / Install our cPanel license to the newly built u20 server first before using the transfer tool? Or this can be done once migration is complete?

I'll keep you posted if this works out well.

You'll have to have cPanel installed on the new machine. If you don't get a trial license for that server and don't want to move your paid license just yet, you can always request a migration license through a support ticket or by contacting [email protected] directly, which is our Customer Service team email.
