To connect to the source server by SSH:

  1. Make sure that an RSA key pair without a passphrase exists on the target Plesk server (the server where Plesk Migrator is installed).

    If not, use the ssh-keygen utility to generate it:

ssh-keygen -t rsa

During the key pair generation, specify the directory for storing it (usually it is /root/.ssh/id_rsa) and do not enter a passphrase.

  1. Copy the public key to the source server using the command:
ssh-copy-id <user name>@<IP address>

Where <root user name> is the name of the user with UID=0 (usually it is root) and <IP address> is the IP address of the source server.

For example:

ssh-copy-id root@
  1. When starting a new migration, select the SSH keys authorization and specify the absolute path to the private RSA key on the target Plesk server. For example: /root/.ssh/id_rsa.
