SalishSeaSecurityAssuming these DCs are active/active meaning you always send requests to both locations based on a GTM load balancing method and 1 site can handle all traffic I would go the route of replacing 1 DC at a time. So you suspend DC1, replace both devices at that DC, perform some testing of the replacement devices, and finally do the same for DC2 after DC1 is back as active in the GTM. I see no reason to overcomplicate this by trying to removed 1 device at a time from each DC if either DC is capable of handling all traffic.
