Converting a cPanel-based server from CentOS 7 to CloudLinux OS

[stevenpicado]

Hello everyone,

I've never posted anything here but I need some help, I have a server running CentOS 7.9 and I have to migrate because end of support will be coming next year on June, I was planning on creating a new server with CloudLinux OS and migrate everything but then I bumped into the following URL:

CloudLinux - Converting CentOS server with cPanel - CloudLinux

This resource explains plain and simple how to make the upgrade that will replace CentOS for CloudLinux OS in a matter of minutes, I believe this is great because I don't have to migrate anything, I don't have to change IP addresses on my licenses and also no updating DNS settings for my system domains.

Obviously I've never done this before so my question is, is there ANYTHING that could go wrong with this process that I should be aware of? Does anyone have any advise you can provide to make the upgrade as safe as possible?

Thanks in advance for any help provided.

Hey there! It really should be a smooth process, and the only interruption would be when you need to reboot the system to load the new LVE kernel. It's always a good idea to have backups just in case, but that's true of any major server change.

Thanks so much for the reply cPRex, I really wanted to confirm this with someone else before I did the change. I'll probably do it over the weekend.

Sure thing! It really should be that simple, as it's a drop-in replacement for your current OS and integrates completely with cPanel.

I would like to hear how did it go? Do you have Cloudlinux 8.x after the convert or older Cloudlinux 7.x?

I thougth the convert path is for "CentOS 7.x => CloudLinux 7.x". Or does it upgrade to the CloudLinux 8.x?

@daynight - the user would have had CL7 if they performed the installation. The installation itself does not upgrade the OS at the same time.

Yup. So the OP needs to upgrade the server anyway because of CL7 has the same EOL date as CentOS 7. Converting the server first didn't really serve any purpose, am i right?

I can't really speak to what his purpose was. The OP was interested in the conversion process causing issues, and the OS still has one year of life left at this point from the vendor, and is good through cPanel 110 which will be the next LTS tier. It is a good idea to upgrade to a newer system to continue to receive cPanel updates.

Oh. I thought the OP was clear. The OP had CentOS 7.9 and the OP needed to migrate because of EOL. Why would the OP want to migrate to CL7 because it has the same EOL. He was just wondering if the convert path would do the trick for him...

Anyway. I'm just asking this because i'm in the same situation. I'm running a CentOS 7 and CL7 servers which i need to upgrade to CL8. I was looking for upgrade path and examples how it's done. Or if there's multiple ways to do the upgrade.

We offer the ELevate project at this time for CentOS 7 machines:
