Hi Sharank,

 

First of you have to set UP a Floating IP on your 3600, Currently your business flow pass trough your selfIP but when you will set your cluster, your Business Flow will pass trough the floating (and monitoring trough self IP).

 

So before to go ahead you must already make your set up the FW rules to avoid any unpleasant surprises during your migration

 

you must add the following IP source: current 3600_self-IP (must already be present) Flating IP 2200_self-IP

 

You need to do the same job with other equipement (mail relay, ...).

 

In bothe device you need to create a new vlan (for HA only) you don't need a floating IP (and don't forget to set self IP Port Lockdown to allow default )

 

Second point (Set UP your 2200):

 

  • System config (NTP, DNS,)
  • Network (Self IP and routing)
  • then Cluster part: follow this footage it will help you
