Unable to start migration: urlopen error [Errno 10049] The requested address is not valid in its context

• Migration fails with the following error:

  Failed to connect to target Plesk server by Plesk API: <urlopen error [Errno 10049] The requested address is not valid in its context> 
  

• On the target server "%plesk_dir%\var\modules\panel-migrator\sessions\<SESSION_TIME_STAMP>\debug.log" has the following data:

  core.utils.common.http_xml_client|||API request to https://203.0.113.2:8443/enterprise/control/agent.php:
  
  ...
  
  core.connections.checker|||URLError: <urlopen error [Errno 10049] The requested address is not valid in its context>
  

• IP address 203.0.113.2 does not exist on the target server, but is listed in Plesk under Tools & Settings > IP addresses

  > ipconfig | findstr 203.0.113.2
  
  > 
  

Cause

Plesk Migrator sends API request to target host to non-existent IP address.

Resolution

In "%plesk_dir%\var\modules\panel-migrator\sessions\<SESSION_TIME_STAMP\config" file change the target IP from non-existent IP address to the correct one:

[plesk]


ip = "203.0.113.100"
