When trying to move subscription from one service node to another it fails with the error:

[2015-07-10 14:17:04,642] [ERROR] parallels || Unexpected error: 'HttpClientError(HTTP Error 504: Gateway Time-out, '<html>\r\n<head><title>504 Gateway Time-out</title></head>\r\n<body bgcolor="white">\r\n<center><h1>504 Gateway Time-out</h1></center>\r\n<hr><center>nginx</center>\r\n</body>\r\n</html>\r\n')', migration is aborted. See the traceback above for more information.


The PA migration tools were installed not on the management node, but on a different server. Some requirements are not met for such a scenario.


We strongly recommend that you install the tools to the management node. All further instructions in this guide are given for the tools located on the management node. Nevertheless, if needed, you may run the tools on any server in your network that meets the following requirements:

  • CentOS 5.x/6.x or Red Hat Enterprise Linux 5.x/6.x is installed on the server.
  • The server can connect to your hosting servers and the PPA management node.

Additional information can be found in the product documentation:
