Hello Johan,
we tested it quickly in our lab (only 1 eaps ring) and it gave no problems. We did see a log event that EXOS was unable to start the new domain as it was already started but that seemed to be the only issue.
10/21/2015 12:55:00.22 EAPSD TAC-EAPS - Event Start. Domain has already been started.
10/21/2015 12:55:00.22 10.112.2.123 (telnet) admin: configure eaps "TAC_EAPS" name TAC-EAPS
I would advice to do this on a quiet time in case something does happen.
Best regards, Oscar
