I have a single deployment of esxi and vmotion is disabled by default but I am still seeing logs for Vmotion. Esxi is deployed on a hosted server that is accessible via public ip address.
WARNING: Migrate: 446: Invalid message type for new connection: 542393671. Expecting message of type INIT (0).

Please help. Happy new year!
Hopefully none of the interfaces on your ESXi host are accessible on the public Internet. If so, that's a huge no no and should be corrected immediately.
