We are in the planning phase for migrating our companies file shares to a new SAN and also a new file server. We are currently sharing them out from a Server 2003 box and an EMC CX300 SAN. We are migrating them to a virtualized environment and the new file server will be a 2012 R2 VM and the storage will be on a new Equalozic P4100 SAN.
My question is what would be the best way to migrate this data, roughly 4-6 Tb, while keeping the data live for the end users? I have read a little bit about setting up DFS, Distrubited File System, and was thinking of using replication to migrate the data. Is this a viable option or is there a better way to accomplish this?
I was thinking of setting up replication from the 2003 box to the 2012 VM and then letting them run that way until all data has been transfered to the new SAN. At that point could we take the 2003 box offline and just run off the 2012 VM?
