LTM - Introduce A/S HA Pair to multiple Admin Partitions

I'm working on adding a redundant LTM to a single platform to form an HA pair. The single production LTM is operating with multiple users/multiple admin partitons.

 

 

My question is:

 

 

Is there a best practice for this scenario?

 

 

If I configure the self-ip, floating-ip, SSL cert/keys, and Redundant config/sync setup in the common partition, Will the other partitions, and user accounts/objects tied to those partitions be pulled down through config sync?

 

 

Do i need to create the user accounts and partitions, and user to partition mapping manually before I config sync?

 

 

Any guidance as far as "Order of operation" is appreciated?

 

 

Thanks in Advance!
