#Snapmirror

I have two volumes on the source system that need to be migrated to the destination NetApp system. The migration process itself is straightforward with snapmirror, and I have no issues with that. However, once the volumes are on the destination system, I need to consolidate them into a single volume.

As per my understanding, ONTAP does not provide a direct method to migrate two source volumes into a single destination volume. Is there any native functionality in the latest ONTAP version that allows this? If not, what are the best ways to consolidate the data from both volumes (200TB) into one after snapmirror is complete, using only NetApp tools and avoiding third-party solutions?

I appreciate your insights.

there's no way to acutally combine them within ONTAP.
Data will need to be XCPed.

Why do they need to be combine?

I ask because most of these questions it's related to splitting the volume or moving it into a flexgroup?.

Ideally the source is on older ontap's where the max limit for flexvolume was 100TB and they outgrown and had to create new volume. But now on new ontap the size of flex volume is 300TB and application wants only one share now to see all their content. @waxen imp

"using only NetApp tools"? Yeah then XCP or CloudSync is the only way. But rsync or RoboCopy would also work if you could use basic OS level tools
If you only need the data accessible in one namespace (and not "physically" in one volume), mounting one volume inside the other would also work. That would still keep them 2 volumes but for the client it would look like a single one

@slim fossil Yup , thought about the tools like rsync and datacopy. Mounting one volume inside the other is not what application team wants. Probably i would end up using rsync. Can we do rsync for DP volumes, i guess not.

What's the model and ONTAP versions of each?

you could always mount the volumes under one single share... either the new one under the old one or both under a "mini-volume"

@waxen imp - Source is on NetApp Release 9.11.1P8 and Dest is on 9.14.1P6.

#

@slim fossil - On the destination once the snapmirror is complete, i thought i will expand the vol1 size to 300TB and do rsync from vol2 to Vol1 by keeping the vol1 content just by adding the data from vol2. For this it has to be RW right?

yeah that should work, but it will take a while (depending on the number of files/directories it can take many hours or even days) so you need a plan on what you do with the clients during that time
