Adding LTM's for migration 11.4.1 HF2
I have a unique situation I'm looking for a little guidance on. We currently are in the process of replacing all of our hardware with new hardware, moving from 8900's to 10200's. What we're doing is creating a side-by-side environment with access to all the same VLAN's and the plan is to add additional LTM instances to a cluster that already has an active/standby setup.
Has anyone ever done this before? Do you just add the additional LTM's to the cluster as a sync-only so they get all the objects and match the current devices? Everything is running 11.4.1 HF2. We will also be migrating the GTM's from 1600's to 2000S devices and hoped to just add the new instances into the current pair of GTM's.
Obviously this is all trying to be achieved with 0 downtime.
Thanks for any tips!
