NimbostratusConfig: HA for Existing One Arm deployment.
HA configuration for existing BIG-IP with One Arm mode deployment.
We have existing 3600 BIG-IP device in One Arm mode deployment.
Now we need to add 2200 BIG-IP in HA with the existing setup.
Please suggest the best practices and kindly share HA config guide for this scenario if any.
Thanks you.

Besides the HA setup, you will need 2 extra IPs per vlan, as you will need a floating IP and non-floating self IP.
In relation to best options for HA, read this solution:
https://support.f5.com/csp/article/K14135I did not understand if you want to do an HA pair between a 3600 and 2200, or you have 2 new 2200.
If the first, read this solution:

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
