Virtual server address space on disaster recovery F5 instance
I am working on setting up a disaster recovery instance of an existing HA BIGIP pair. I would like to ConfigSync (sync only) my local devices to the new device which is located in a different data center. The issue is that if/when I needed to "fail over" (manually) to the new disaster recovery device, the IP space of the virtual servers are different. So for example if my virtual server "A" has a destination address of 192.168.1.10 in my existing data center, the new destination address might be 10.1.1.10. (Note: I am less worried about pool member IP space, because I can use priority groups and have the disaster recovery pool member IPs pre-configured but disabled). My first thought was a "DR go live" script which would search & replace the config file and reload it, but is there a more "elegant" way to handle this dilemma, without having them have the same IP space?
