Purpose

There are messages on charging nodes in the passive site that indicate a connection migration:

Oct 24, 2019 8:05:16 AM com.oracle.common.internal.net.socketbus.AbstractSocketBus$HandshakeHandler$1 run
WARNING: tmb://IPAddress.51:20093.49833 accepting connection migration with tmb://IPAddress.6:20095.53758, replacing MultiplexedSocketChannel(MultiplexedSocket{Socket[addr=/IPAddress.6,port=20095,localport=60912]}) with MultiplexedSocketChannel(MultiplexedSocket{Socket[addr=/IPAddress.6,port=47800,localport=20093]}):

However, the second address corresponds to a server in the active site, rather than the passive.
The user did replication through gridSync from the active to the passive site and has some questions to be clarified as below.

Questions and Answers
 What these error messages mean and why they could be occurring?
 Why is it migrating the connections between nodes from the passive site to the active side?
 Does the replication process establish TMB connections between nodes from different sites for the transfer of data when replication is active?
 What exactly could it mean that these messages appear with certain frequency? Could it be related to poor performance on the cluster that connections are getting migrated?
