Testing Exchange 2010 iApp
I currently have Exchange 2010 deployed on 10.x using an older iApp in two datacenters. In my primary datacenter, I want to migrate load balancing to a new v11 platform using the newest iApp.
I see two options for deploying and testing the iApp on the new v11 platform:
1) Pre-create the virtual addresses on the v11 boxes and disable ARP. Then, I can run the iApp and use the production VIP's that are already in use on the v10 platform without causing traffic interruptions or ARP conflicts. When I'm ready to cutover to the v11 platform, I can disable ARP for the virtual-addresses on the v10 box, and enable ARP on the v11 boxes. However, I won't really be able to test the new v11 iApp deployment using this method.
2) Use the new iApp template on the v11 boxes using NEW VIP's. This will allow me to test the deployment to some extent. Once testing is completed, I can disable the VIPs on the v10 platform, and CHANGE the IP's of the VIP's on the v11 platform to match the production/v10 IPs. Do you think it would be as simple as this (just re-iping the virtual servers?).
Any thoughts or suggestions on either of these options?
