MySQL replication master port change

I have 4 servers running MySQL 5.6. A,B,C and D. A and B are Master and slave whose default port is 3306. C and D are running in non-default ports 3360.

A and C are in Master-Master replication mode. C and D are in Master-Slave setup.

Now I need to change the ports on A and B from 3306 to 3360, what commands I need to run and in what order to have B,C and D back in replication?

Is the below steps right?

1. Stop the slaves in B, C and D.
2. Stop A and change the port in A to 3360 and start A.
3. Stop B and change the port in B to 3360. Ensure skip slave start is set to true.
4. Start B and run change master to master_port=3360 and start slave.
5. In C, run the same as step 4.
6. Start slave in D.
