Upgrade Cloudlinux 7 in place?

[Jordz2203]

Hey everyone, wanted to find a bit of information here. With CentOS 7 being end of life. Our Cloudlinux server running Direct Admin needs to be uprgaded. I dont actively maintain this particular server anymore. But wanted to help sort it out. So I have a couple questions and would be great if someone can help:

1. What is the best version to upgrade to? (We are on Cloudlinux 7.9)
2. Is it possible to do an in place upgrade? (I saw a cpanel thread saying the cloudlinux script to do it does not work anymore, and I want to avoid downtime and doing a massive migration and fresh install).

If you really want to avoid down times, you need to prepare anouther server as new version OS like CL8, ( "CL9" have a little weird problem ) and install everything in their.

After your new server is in ready state, enable maintenance mode in old server to avoid database write/update new data while transfer into new server.

Then use the Admin backup to restore via FTP transfer from the old server.

this will only down times on transfer/restore backup process.

You can even do a tranfer/restore of only the user profile and save time to sync the web/email data by rsync. So you can do a sync in the meantime and a final sync and import the databases last. In my experience this creates the least downtime.

1. Version 8 is safer for now.
2. You can upgrade directly from 7 to 8. The importances are:
- Backup everything before doing anything.
- Read and make sure you understand everything that the pre-check script gives you.

@Imtek's solution is by far the best way to go about this.

Thanks, we have been doing this a lot for OS updates and it works fine or even creating a full server sync from physical to virtual or visa versa.

How do you do that? Import the database for all users as last thing after restore?

Just create a backup of the user without the website and email data.

without the website and email data.

Ah oke. So userstuff with rsync and data with the DA backup. No special method with a mysql command. I thought you were using something like that.
In our case biggest content is mostly e-mail. So we backup all accounts and website data without mail and then restore mail with rsync.
