Migrations and Floating IP's

Thanks, yea the problem cropped up when I moved some systems over and those systems actaully have to communicate with some siemens workstations out in the hospital. I am not sure if those workstations have some type of approved list and they only accept connections from a specific IP or what. Still trying to get more information. I will conitnue with the migration and then schedule a downtime, unplug all of my uplinks on the old HA pair and change the floaters on the new pair to match. Thanks
