A load balancer can cause an unexpected connection termination.

Problem

Some load balancers have very short timeouts for keeping a connection alive during execution of an HTTP/HTTPS request. This short timeout can result in unexpected connection termination when migration performs long-running operations.

Procedure

Increase the timeout on the load balancer or update the load balancer DNS record to point to the appropriate active node for the duration of the migration. Once migration is complete, revert the load balancer DNS record.
