Hi There,

I currently have this situation in hand.We are now in the midst of working out a solution to refresh customer existing NS-120 – one in Egypt and one in Malaysia with one VNX5200 each. Currently the NS-120 is replicating to the other NS-120 using replicator (file only configuration – both NFS and CIFS shares). We are now trying to finalize the migration approach and we want to seek your guidance on this. Constraints that the customer has is that the bandwidth between Egypt and Malaysia is very small (to do a full initial sync between sites is difficult) and tape silvering is out of the question (they are using Backup Exec which is not supported).

Initial plan was to ship two VNX5200s to Egypt, do the sync locally on site in Egypt and ship back one of the VNX5200s to Malaysia but obviously it is a very expensive way logistic wise to do so

There was another suggestion  to

1. move the data from NS-120 to VNX5200 would be via  IP/VNX Replicator at each site.
2. Once both sites has been replicated and cut over to the new VNX5200, we will then create a new  replication set and replicate  back from Egypt’s VNX5200 to Malaysia’s VNX5200 incrementally. Is this even possible?  With data already in the VNX5200 filesystem now, would we be able to perform a incremental SYNC update from Egypt's VNX5200  to Malaysia's VNX5200 or will it be a Full SYNC?
