Change iSCSI Initiator Target Portal IP

I have an equallogic with four interfaces (eth0-eth03). Eth3 is dedicated for management and its a separate subnet. Each server has multiple iscsi interfaces.  The interfaces contains old IP address and new IP address which are both outside the same subnet.

I need to update the target portals and the equallogic group IP with a new IP address on the new subnet.  I changed eth0, eth2 to the new IPs in the different subnet.  Now all the equalogic MPIO interfaces are pointing to eth1 from the servers.  

How can I minimize the downtime of manually going through the servers to point the iSCSI initiators to the new "target portal" after changing the "Group IP" in the PS Group Series Manager?

What type of security did you put in place initially?  Did you lock it down to a single IP initiator client per virtual disk?

Two switches connect to the two interfaces on each server.  The two switches only contains connection to a one network-the iscsi vlan which then connects to the SAN.  In the group manager on the equalogic, it's configured to limit access to each volume by the imitator name.  I'm not sure if that answered the question....

it does, in that case your security is topology agnostic.

As long as you can reach the new IP group, you can connect.  

On the client side, you will need to clear the old configuration and then re-add it with the new target.

Just be careful, note the drive letter on each server.  Drive designation is random orderly.  Your application path needs to be the same if you had installed applications on those iSCSI drives.

Is there any way to save/backup the targets and such within the iSCSI initiator?  Change the portal IPs then reupload the changes or will it just be as simple as selecting the discovery tab, and add each interface to the new target IP?

Some of the servers, if I click on the details of the current connection, shows Round Robin, one cluster environment shows Failover Only, and another one is Least Queue Depth.  Will each of  these Load Balance Policy become configured automatically after supplying the new target IP?

The initiators include ESX/ESXi hosts?
