Parallels

Symptoms

During migration using PMM you get the errors like: 

    Failed to upload the migration agent
    Cannot send scout to the remote host
    Lost connection with the remote host

Cause

These errors means that migration manager failed upload agent to the remote server or the connection with the remote server was lost.

Resolution

Make sure that you are migrating from the supported platforms:

• Confixx 1.65, 2, 3
• CommuniGate Pro
• earlier releases of Plesk and Slash (for FreeBSD or Linux)
• Cobalt Raq 2, 3, 4, 550, XTR
• cPanel 9, 10, 11
• Ensim 3.5, 4, 10 (experimental, should not be used on production servers)
• Hsphere 2.4.2
• Plesk for UNIX

Note, migration from Plesk for Windows to Plesk for UNIX is not supported.

Plesk Migration Manager uses SSH protocol for migration agent uploading and dump retrieving. Please make sure that:
- SSH server is running and SSH (22) port is opened on the source server (you are performing the migration from),
- SSH server on the source server allows connecting it with SSH version 2 protocol,
- you are able to login from destination server to the source one via SSH under the user you specified during the migration. Also check that you can transfer a file from the source server to the destination Plesk server with `scp` command.
