migrate Data

need to decommission the nodes by replace the new nodes in same cluster. Ex: we have 6 node cluster and need to replace with new 6 nodes and decommission the old  nodes. is it possible to migrate data and cutover without outage?


Re: migrate Data

How many connections do you have on your cluster switch available ? 

Re: migrate Data

It wasn't mentioned what you are upgrading from/to. There are several methods and generally the cleanest way is probably just to do an in-place head swap. You can also as mentioned add the nodes temporarily to the cluster, or even hook up a second cluster and SnapMirror everything over.


If you're working with your account team on this, generally they include PS hours to do the install for you, or they may have guidance for your specific workloads. I'd suggest working with them on the best methods.
