Well... You have more options than v10.
I have implemented this with sync-failover and using an HAGroup to ensure that the DR box doesn't takeover the service UNLESS it detects something that tells it your'e IN DR (For this network it was access OUT form the DR network to the regular network. If it was able to access then the DR took over. If not, the DR was still isolated and wouldn't go active).
However HAGroups are a bit of a pain... In 11.4 you can just specify the devices in the order you want them to be used. Just list the DR box as the last one in the sequence...
