We have 3 ESA (one C300 and 2 C350) working in a cluster mode, two of them with an MX record of 50 and another one with 40. And also a C650 for cetralized management. We need to move them all to another data center. The move will take about 2 or 3 days. they will be given with new MX records in the new location.
What is your recommendation for moving them? Can we take first the two devices with hightest cost (50) leaving only operational one ESA and the SMA? or would you recommend to move first one ESA with the SMA, leaving operational the other 2 ESA?
With respect to configuration, do we need to do something for the movement? I think we will need to disconnect all devices from the cluster before moving them, right? otherwise when the first two devices are moved to the new location there can be issues. I have no expirience on SMA, what should I do in order to move it? what considerations should I take?
Thanks in advance for your help!
