How to change the number of simultaneous threads during migration?

Answer

Warning: Increasing the number of threads may cause unpredictable issues on the source server and it is strongly not recommended.

To change the number of simultaneous threads do the following:

1. Start the migration via GUI;
2. After preparing the migration, when the list of subscriptions is displayed:
   1. Connect to the target server via SSH;
   2. Open /usr/local/psa/var/modules/panel-migrator/sessions/<timestamp>/config.ini file in a text editor.
   3. Add the following records in the bottom of [GLOBAL] section and save the file, for example, to set the number of threads equal to 3:

      CONFIG_TEXT: [GLOBAL]
      multithreading-status: full
      multithreading-num-workers: 3

3. Continue the migration via GUI.
