Replicating to new Celerra

I have an NS80G at my main location, and have four NS20s at various locations that are all replicating to the NS80G. I am getting a new NS-480 for the NS20's to replicate to.

My question is, if I simply point the NS20's to the new NS-480, the intitial replication will take quite some time. Is there a way to copy the replicated data from the NS80G to the NS-480, which would in essence seed the NS-480 so the only thing being replicated from the NS20's would be the delta's?

Thank you!

should be possible

take a look at Using EMC®Celerra Replicator¿ (V2) manual and search for silvering

Also from what I understand new deployments of the NS-480, which require replication from older models, should be downgraded from 5.6 code. After the migration is complete the code can then be upgraded

You can't downgrade a NS-480 to 5.5 - it require a minimum of DART 5.6.41

My bad I was told by my EMC SE that in order to migrate data from an older NS to the new NS that the code levels had to be equal. So perhaps the older must be upgraded.

Thanks for clearing that up Rainer

Thanks Ranier. It looks like silvering may be what I'm looking for. I'll need to test this first, but from what the tech module says, it looks like it should work. I'll repost once I get testing done, but it may be a while before I am ready to test.

Celerra replication will require the arrays be running the same family of NAS. So 5.5.x can replicate to 5.5.x and 5.6.x can only replicate to 5.6.x; 5.5 cannot replicate to 5.6 and vice versa. If your current arrays are running 5.5.x they will need to be upgraded to 5.6.x to replicate to the new Celerra you are getting.

Now you can have replicator v1 still running with 5.6 but the rules above still apply so thats not a work around.
