    Technical Advisory - Plesk Panel 10 Migrations

    If you are planning a migration from Parallels Plesk Panel to cPanel & WHM in the near future, do not upgrade Plesk Panel to version 10.

    Parallels Plesk Panel 10 incorporates a new authentication model that does not rely upon the /etc/passwd system database. This change prevents successful migrations from Plesk 10 systems to cPanel & WHM systems.

    The cPanel & WHM development team is working on a solution to include in future releases of cPanel & WHM.

    Our migration team currently supports migration from the following platforms:
    • DirectAdmin (all versions)
    • Ensim / Parallels Pro (all versions, Linux Only)
    • Plesk (6 - 9.5.1, Linux Only)

    But still nightmarish. Just went through that in closing up an older Plesk server. Had to do lots of manual work to get it to function reliably, particularly with databases.

    Best to stay away from Plesk if you can.

    Peace,

    Hi Gene,

    Thanks for your feedback.

    Did you do this migration yourself, or did you take advantage of our free migration service? The reason I ask is because I am interested in learning more about the issues that you experienced. If you used our migration service, can you please paste the ticket number(s) here? If you didn't use it, and if you have a moment, can you please open a ticket on our helpdesk with the details of the issues that you ran into (see my signature for the link)?

    In either case, thank you again for your feedback - it is always welcomed and always appreciated!

    I had a colleague do some of the heavy lifting, and I did the easier stuff. The cPanel server already had existing accounts (older versions of the ones on the Plesk server), which makes it ineligible for your free service, apparently.

    The problem with the Plesk server was that the contents were originally migrated from cPanel some months back. The Parallels migration manual suggests you change the site file locations from the Plesk default (/var/www/vhosts/) to /home to match the cPanel methodology. You have to change a PSA settings file to reflect the new destination, and run a couple of scripts to manage the rest of the process. The drive used LVM formatting, which made it easy to rejigger the sizes of each partition.

    That change seemed to confound your transfer capability, since cPanel apparently expects to find the files in the standard location. In the end, since only 8 domain/accounts were involved, and older versions of the same sites were on the cPanel server already, it was mostly a matter of manually updating databases, moving recent email, and updating some site files. Sounds like a mess, but we got the majority of this done in a few hours and there was no downtime in the DNS transfer.

    In the future, I wouldn't be caught dead using Plesk. I won't begin to explain to you what issues were found in that environment, even though we had the latest and greatest version (10.2).

    Peace,
    Gene

    Thanks for the detailed info, Gene. We do appreciate it.

    That does help clear things up a bit. I can see how there would be issues with accounts moving from cPanel to Plesk and back to cPanel. As you've described the process of migrating cPanel accounts to Plesk, I concur that the issues in getting them back to cPanel were due to the changes made. I applaud your tenacity in getting the accounts moved back over. Welcome back to cPanel-ville. We do hope you enjoy your stay.

    If you have any questions - about anything - please feel free to let us know at any time. We'll be here :)

    It's more complex than that. The original group of WordPress and vBulletin sites started at GoDaddy, went to DreamHost, and managed several transfers across cPanel and Plesk as we moved to larger servers.

    But I don't plan to write a novel about it. I've done quite enough books for now. :D

    Peace,
    Gene
