Migrate OA & Blade iLO interfaces to new VLAN

Hi,

I'm looking to move our enclosure and iLO management to it's own separate VLAN so it's away from the standard 'server' VLAN and am looking for direction in terms of the steps taken, and also whether there's anything else I need to consider.

My environment consists of 3 x c7000 (linked) enclosures, each with 2 x Flex10 Virtual Connect modules and 2 x OAs.

My thinking is as follows:

1) Configure new VLAN on switches and identify ports used for the OAs.
2) Log on to OAs and change IP addressing to new IPs associated with the new VLAN. At this point I lose connectivity (I'll be doing this remotely).
3) Change the switch ports that connect to each OA to be access ports in new VLAN. At this point I should regain access to the OAs on the new OA IP addresses.
4) Change the blade iLO IP addressing to the new VLAN.
5) Change the Flex10 IP addressing to the new VLAN.

Does that all sound correct?

Is this a disruptive task, as in, will it impact any production network traffic?

Thanks in advance.
