Hey Jurgen, Thanks for the response! Yea no Active-Active MYSQL… That’s suicide with no conflict resolutions.
How do you balance the traffic between the Geo Redundant ACS Setup? Im guessing this is only convenient if you use subdomains in your CS Agents, is that what you managed to achieve? I’ll look into the multiple mgmt servers again, I couldn’t get it working the last time.
