Question

How to speed up a Plesk migration?

Answer

The time effort for a migration depends on the following:

  • amount of the migrated data

  • network bandwidth

  • server performance

 

To speed up a migration, consider to:

  • Increase server performance:

    - stop all tasks/processes that are not necessary to run
    - suspend domains before starting a migration. This should only be done in case the websites are allowed to be unavailable while the migration is running.

  • Improve network performance:

    - speed up SSH connection by contacting a network administrator for increasing network connection speed

  • When migrating via a command-line interface, reduce the amount of data:

    - transfer domains by small bunches (5-10) at once

    Plesk onyx restore is very slow than before. 80 mbs takes around 20 minutes before it used to be 1 or 2 maximum.

    Hello @James,

    Such behavior is not typical for Plesk Onyx.

    To investigate the issue consider contacting technical support.

    I have migrated below data it takes 18 hours to complete its really slow even both servers in same network.

    Both server having dedicated 3 MBPS connection speed

    Disk usage 52.7 GB 
    Traffic 4.65 GB 
    Active domains 130 
    Domains 151 
    Subdomains 68

    Migration speed may differ based on the many factors, such as the type of data transferred.
    IO operations on small files, for example, tend to be way slower due to the way how file systems work.

    You can speedup this by following steps

    1. Copy your subscription folders from C:\inetpub\vhosts and put those directly on new server and keep somewhere other than C:\inetpub\vhosts
    2. Move/Delete Copied Subscriptions from old server
    3. Now Create and Download Backup from old server( Tools > Backup Manager )
    4. To Restore accounts Run This command on new server from cmd  ( plesk bin pleskrestore --restore C:\Users\Administrator\Downloads\backup_info_2005050516.xml.zip -level server -ignore-sign -ignore-backup-password ) here the backup file is backup_info_2005050516.xml.zip
    5. Once restore complete move subscription folder backup to C:\inetpub\vhosts (ref. step 1)
    6. Done

    Thank you for sharing the scenario you're using.

    However, step 1 still requires manual data transferring and that will still depend on network and hardware speed. Pretty much the same as for migration.

    The link above to speed up migration doesn't work anymore. (https://support.plesk.com/hc/en-us/articles/360002473293 - "You're not authorized to access this page") The migration process was working fine in the past. Super fast with NVME drives and plenty of CPU, RAM and minimum 1G dedicated network for migration. Right now it's a nightmare and runs on a single thread only. Disabling the PSA Backup low prio limitation doesn't seem to help.

    So how can one speed up migration ?

    Thanks
