Disastser Recovery

Hello everyone,
 need to implement a Disaster recovery solution for a customer.
 I read the solution K39543431  but there are some points that are not clear for me.
 In order to build it,
 I need to configure the same vlans that are present  on  active/stand-by  to disaster recovery devices,  so that  I needs to configure, for each vlan, only self ip.
To sum up:
the disaster and recovery device needs to reach all vlan configurated on the active/stand by device . 
it needs to be add as peer and configured as part of traffic group - in this way is possible to sync everything.
Is it correct ?

Someone knows if there is a guide or tutorial that is possible to download for having major information about how to do it ?

Many thanks everyone for your time and consideration.
Awaiting news.
Rgds,

    in the prerequisites of  K39543431 it is written: "You configured your disaster recovery remote environment with duplicate resources used in the HA environment."
    I understand that you have the same VLANs, but also the same backend systems, with the same IP addresses. Not only pool members, but also DNS, NTP, syslog servers.
    And also you can use the same virtual IP addresses in your DR site, because your DR router and your DR firewall can route these IPs.

    In my opinion a totally obsolete concept, to have a warm standby site like this. Unless you have some regulatory requirements for this kind of setup, it's a total waste of money. And also if you must have such setup because of regulatory requirements, it's still a waste of money.

    A more contemporary way of keeping your config in sync in a DR site would be the use of automation and AS3.
