Cannot login to Plesk via WHMCS after migration: Customer with external id 'whmcs_plesk_XX' is not found in panel

Applicable to:

  • Plesk for Windows
  • Plesk for Linux

Symptoms

  1. Migration Plesk to Plesk was performed.
  2. WHMCS is used on the server.
  3. The following error is shown when accessing user with login 'example' in Plesk via WHMCS:

    PLESK_INFO: Error code: 1013. Error message: Customer with external id 'whmcs_plesk_XX' is not found in panel.

  4. External_id is missing for the user with login 'example':

    MYSQL_WIN: mysql> select external_id from client where login='example';
    Empty set (0.00 sec)

Cause

This is caused by the Plesk Migrator bug #PMT-3035 which been already fixed for all versions.

Resolution

As a workaround, update external_id via command line:

Plesk for Windows:

  1. Connect to the target server via RDP;

  2. Copy sample configuration file from the %plesk_dir%\admin\plib\modules\panel-migrator\backend\conf\samples\plesk-windows.ini file to the <PLESK_DATA_DIRECTORY>\var\modules\panel-migrator\conf\ directory. To find $PLESK_DATA_DIRECTORY location on the server use the following command:

    C:\> reg query "HKLM\SOFTWARE\Plesk\PSA Config\Config" /v PRODUCT_DATA_D /reg:32

    Note: If the folder <PLESK_DATA_DIRECTORY>\var\modules\panel-migrator\conf\ does not exist, create it and place the file into it.

  3. Rename plesk-windows.ini to config.ini

  4. Specify IP addresses of source and target server and their credentials in config.ini file, for example:

    CONFIG_TEXT: [plesk]
    ; An IPv4 address of the target Plesk server.
    ip: 203.0.113.200
    ; Panel administrator's login. If not specified, 'admin' is used.
    ; panel-username: admin
    ; Panel administrator password. If not specified, it is automatically detected.
    panel-password: required_password
    [pfw]
    ; An IP v4 address of this source Plesk server.
    ip: 203.0.113.300
    ; Panel administrator user name. If not specified, 'admin' is used.
    ; panel-username: admin
    ; Panel administrator password. If not specified, it is automatically detected.
    panel-password: required_password
    ; User name of the privileged system user on this Plesk server. Default is 'Administrator'.
    ; windows-username: Administrator
    ; Password of the privileged system user on this Plesk server.
    windows-password: required_password

  5. Generate the migration list:

    C:\> "%plesk_dir%\admin\plib\modules\panel-migrator\backend\plesk-migrator.bat" generate-migration-list

  6. Update external_id on the source server:

    C:\> "%plesk_dir%\admin\plib\modules\panel-migrator\backend\plesk-migrator.bat" set-external-id

Another solution:
  1. Login to the source server via RDP.
  2. Generate list of client's and their external id's:

    C:\> plesk db -NBe "select login,external_id from clients where parent_id = 1 and (external_id != NULL or external_id != '0' or external_id <> '')" > C:\clients.txt

  3. Copy C:\clients.txt from the source server to destination one.
  4. Login to the destination server via RDP.
  5. Create backup of psa database:

    C:\> plesk db dump psa > C:\psa._before_clietnsExtId_update.sql

  6. Execute below command to update client's external id on destination server:

    C:\> for /f "usebackq tokens=1,2" %a in (C:\clients.txt) do plesk db "update clients set external_id='%b' where login='%a'"

Plesk for Linux:

  1. Connect to the target server via SSH;

  2. Copy sample configuration file from the /usr/local/psa/admin/plib/modules/panel-migrator/backend/conf/samples/plesk-unix.ini to /usr/local/psa/var/modules/panel-migrator/conf/ and rename it:

    # mkdir /usr/local/psa/var/modules/panel-migrator/conf/
    # cp /usr/local/psa/admin/plib/modules/panel-migrator/backend/conf/samples/plesk-unix.ini /usr/local/psa/var/modules/panel-migrator/conf/config.ini

  3. Specify IP addresses of source and target server and their credentials in config.ini file, for example:

    CONFIG_TEXT: [plesk]
    # This section defines target panel settings.
    # [mandatory] ip
    # An IPv4 address of the target Plesk server.
    ip: 203.0.113.200
    [pfu]
    # This section defines settings of source Plesk server 'pfu1'.
    # [mandatory] ip
    # An IP v4 address of this source Plesk server.
    ip: 203.0.113.300

  4. Generate the migration list:

    # /usr/local/psa/admin/sbin/modules/panel-migrator/plesk-migrator generate-migration-list

  5. Update external_id on the source server:

    # /usr/local/psa/admin/sbin/modules/panel-migrator/plesk-migrator set-external-id

    We have the same issue on Linux too. Moved few servers from old Centos to new with Ubuntu and lost all external id's for WHMCS. It's alson not only on Windows.

    Hi @Miomir Besarabic!

    Indeed, this issue is related to Plesk Migrator extension rather then to operation system, I have updated the article with this information! Thank you.

    However, In order to avoid it, the same steps should be used, the only difference is the location of the configs, it is /usr/local/psa/admin/plib/modules/panel-migrator/backend/conf/samples/.
