Applicable to:

  • Plesk for Windows

Symptoms

  • Migration is stuck at the very beginning with starting migration message and nothing is coming up:

  • While trying to reload source server data from the command line on the target server, it finishes successfully:

    C:\> "%plesk_dir%\admin\plib\modules\panel-migrator\backend\plesk-migrator.bat" generate-migration-list "C:\Program Files (x86)\Plesk\/var/modules/panel-migrator/sessions/<datetime>/config.ini"
    ...
    [INFO] FINISH: Generate migration list file
    [INFO] Perform final clean up

  • The%plesk_dir%\var\modules\panel-migrator\sessions\<datetime>\config.ini file contains the following information regarding the user credentials for the target server:

    CONFIG_TEXT: [plesk]
    ...
    windows-username = "admin"

  • The specified user does not exist on the target server at Start > Computer Management > Local Users and Groups > Users

Cause

Incorrect build-in administrator user is provided for the migration, however no warning was shown.

This is a Plesk bug #PMT-3961 which is planned to be fixed in future Plesk updates.

Resolution

For migration via the graphical interface:

  1. Log into Plesk.

  2. Cancel the current migration session in Tools & Settings > Migration & Transfer Manager.

  3. Start a new migration session specifying credentials fo built-in Windows Administrator.

For migration via the command line or via GIU, without finishing the current session:

  1. Log in to the target server via RDP.

  2. Edit %plesk_dir%\var\modules\panel-migrator\sessions\<datetime>\config.ini file with any text editor and replace admin user with the server's built-in administrator login user:

    CONFIG_TEXT: [plesk]
    ...
    windows-username = "Administrator"

  3. Log into the Plesk.

  4. Go to Tools & Settings > Migration & Transfer Manager and proceed with the migration.

    I tried this solution, but then I get the error that login or password is wrong, so the login was probably correct and this solution not?

    Hello @Bart Van Sichem,

    It is possible that in your case migration hangs due to a different cause.

    I can suggest submitting a support request to find the root cause.
