F5 LTM/APM Disaster Recovery Options?

I personally built our DR setup into the main cluster so everything synced nicely.
LTM may be a issue to do that, but APM still might let you sync the config to the DR devices for you. 

One thing i considered when doing this is how the DR site would be triggered, for me it was fast so i set things up so it was a couple of button clicks rather than a set of work and testing.

I must admit i'm about to go and look at the scf i might have a use for that somewhere else!
