Hi Chris,
I think something like this would work:
- back up the existing DR unit config to a UCS using 'b config save dr.ucs' or 'tmsh save /sys ucs dr.ucs'
- export the production config to an SCF using 'b export prod.scf' or 'tmsh save /sys scf prod.scf'(v10) or 'tmsh save /sys scf my.config.scf' (v11)
- copy the SSL certs/keys from /config/ssl/ to the DR unit
- edit the SCF on the DR unit to modify the IPs and load them using 'b import prod.scf' or 'tmsh load sys config' (v10) or 'tmsh load /sys scf my.config.scf' (v11)
If your DR site is a single unit, you would need to modify the HA config.
