Moving 3 ESA and 1 SMA

Question

Hello,
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!
Best regards

Hi Victor,
There is really not much to the SMA, I don't think I have even seen a guide for it!! the SMA can't join your cluster of appliances. All the settings you mention such as IP, Gateway etc. are specific to each ESA anyway, they are not cluster settings with the exception of DNS but you can create a group for it, if the appliance will be talking to each other when they are in different locations. I would not break the cluster just disconnect that one appliance you are taking, once you have two or more appliances in the same location you can reconnect. Just try not to make any major changes that way you don't create inconsistencies in the cluster.
Question 1: is it possible to join this ESA remotely to the SMA althoughit is not in the same cluster? Ans: As long as the SMA can communicate to the designated ESA via one of the protocols specified such as SSH and the right credentials are used, it does not matter where each box resides. Remember your SMA is not joining your cluster, you are simply pointing your SMA to gather info from your ESA and configuring your ESA to send off-box quarantine etc.
Question 2: is it possible to move local quarantine files from the ESA to the SMA? I thinking in the we might have alone for one week one ESA, and then we would need to move the local quarantine files to the SMA.
Ans: I don't think there is a way to move existing quarantined files from the ESA to an SMA I have explored that route before and have been unsuccessful, what I ended up doing was suspending the listener of one appliance at a time so no new incoming mail would come in, leaving the on-box quarantine on so the users can access it, and waiting until the specified purge time, and then after pointing to the SMA for off-box.
Hope it helps in some way. ;-)
