    Good morning,
    I have a problem with the ISPConfig migration tool.
    I have an old Server (source) with a Debian 7 in production, from which I wanted to migrate the mail, web services.. to another new Server (destination), then clean installation of Debian 12.11 and new ISPconfig.

    The problem is the following, I start the migration tool, but at the final moment it gives me a loop in the SSH access.

    I checked the destination Server and it only has "PermitRootLogin to yes" in the sshd_config file.
    I kindly thank you in advance for the help and support

    Doing from the source server:
    "ssh -p 22 [email protected]" and entering the password works regularly

    UPDATE Today 13/06
    If it can be helpful, I tried to run a migration test always from the same Source server, but to another Destination server with Debian 11.10 and the (dry) test worked correctly.

    Code:
    Now try logging into the machine, with "ssh '-p 22 -oStrictHostKeyChecking=no -oConnectTimeout=5 [email protected]'", and check in:
    
      ~/.ssh/authorized_keys
    
    to make sure we haven't added extra keys that you weren't expecting.
    
    What is the ip for the target mail server to connect via SSH? [xx.xx.xx.xx]:
    What is the SSH port? [22]:
    
    Now we transfer the key to the target server.
