I have a site where NBAC is confirgured and running on 7505. I am upgrading to 7601 on the Master Server initially (after completing the Ops Center Server OK) and following the first phase of the upgrade when I go to launch the Admin Console to check on the Phase 2 conversion I cannot access the Admin console - getting the message "unable to retrieve the version of the server <master serever name>".
I saw the technote relating to requirements for upgrading to 7.6 when NBAC is in use, and it simply states that you should keep the AT & AZ services up when commencing the upgrade and all will take care of itself.
I did a bpdown and all services were stopped. I then restarted the AT & AZ services (which also started the Relational DB Manager service) and started the upgrade. One of the first steps of the upgrade however runs a bpdown which stopped all 3 services again. I did see the steps during the install stating that NBAC was being upgraded (which took a few minutes) - but after all completed OK I am in the situation whereby I cannot launch the Admin Console.
Any advice ?
