Hi,
we just received a new 3140 cluster here to upgrade an existing 3020c
production filer. And now we're looking for a way to migrate the
existing data (~18TB) with the least possible downtime.
Ideally, we would use SnapMirror to copy the data on the new filer and
then transparently (for clients) switch the production system,
similarly to what happens when a cluster member fails over to the other
member. But we don't know if this is possible.
So the questions are:
- do you think such a procedure could be successful ?
- do you have any other ideas to migrate the data without service
interruption ?
Cheers,
Simon
