Migration Failure: Internal App Transfer Error
Error: Data migration failure: internal: Cleaning up failed app transfer from destination server
This error occurs when the source server is unable to establish a secure, uninterrupted data stream to the destination server. During an application role move, the servers must communicate directly to synchronize container data and file systems.
Troubleshooting Requirements
Hardware/External Firewalls
If your destination server is behind a hardware firewall or a Cloud Security Group (AWS, Azure, etc.), you must ensure that all traffic is allowed from the Source Server IP address. Restricted port access will cause the transfer stream to time out and trigger a cleanup.
SSH Port Configuration
LxRoot's migration orchestration expects the destination server to be listening on the standard SSH Port 22. If you have changed the SSH port to a custom value on the destination server, the automated transfer will fail.
Before attempting the migration again, verify connectivity by running a ping or a telnet {destination-ip} 22 from the source server's command line to ensure the path is clear.
