Modify Zone Configuration on Brocade switch

We need to modify the zone configurations on our redundant fabrics. My upper management has some concern that if we would do both fabrics at the same time (in sequence, as opposed to the exact same moment) that something could happen and then our infrastructure could be compromised.

They would rather have us do the zone reconfiguration on fabric A during one maintenance time window (this weekend), and the other fabric zone reconfiguration during another maintenance time window (the following week).

When our maintenance window is 3:00-6:00am on Sunday morning, I would just as soon provide some best practice or technical reason why this doesn't need to happen in separate windows, but is safe to do during the same window.

Any suggestions on white papers or best practices would be welcome.

Not at the same time is ok, since it can be disruptive, so when 1 is down, the other is up. Be aware that all hosts need to be attached to both fabrics, so they'd be able to reach their storahe over at least 1 HBA / fabric.

After your work on 1 fabric, test connectivity on all hosts to be sure the number 1 fabric is really up and running and after that you can do the number 2 fabric.

You should be fine doing it in this order.

I replaced old Brocade switches with new Cisco's a while ago and did it like this: there was no downtime !
