Single Server DNS to HA Appliance Solution
We have three locations with a single DNS/DHCP server at each site. We decided to go to a HA appliance solution since the we're rapidly growing taking on new business daily. The Virtual IP of the appliances will be the production IP address of the single servers. Theoretically nothing is changing. Just the devices themselves. To the users, this is transparent, we're hoping.
Since the IP addresses are not changing, what type of issues will we see, if any? Will it be a smooth cutover? Just wondering if anyone has done this. thanks in advance.
This is internal DNS and not an external change.
