Move a HP SAN Enviroment to a new Subnet

We have one physical Blade Enclosure with 8 HP BL460c Blade Servers enclosed.  

This enclosure links to a HP SAN containing 16 300GB SAS HD's with two virtual disks (OS & Data).  

This HP environment is setup on one big flat network which we are now breaking down into multiple VLANS with all server equipment being moved into its own subnet.

No IP address will change but each VLAN will have its own default gateway and Subnet Mask thus I will need to change this for every item currently on static IP address.

From the perspective of the HP Blade/SAN environment is that I will include:

Blade Servers
FC Switches
SAN Controllers
Blade Enclosure

Is there an order I should follow for this change?  Or any advice or knowledge I should be aware of going into this change?

I would put the blade enclosure OAs, blade iLOs, FC switch management ports and any other management ports on a single management subnet, these have very little traffic and are for management and monitoring only so they shouldn't be mixed with production traffic. The servers don't even talk to them although you may have a management workstation that could be on that subnet.  As far as the rest which is production it's really down to function. Your switches are FC so that doesn't come into it except for the management, if there was iSCSI that would be on one (or in many cases two) separate subnets just for iSCSI.
