You can qtree SnapMirror between trad & flex vols if you are using qtrees and you do not want to use ndmpcopy.

However, does not overcome your issues with snapshot retention .....

I think the choices are

use trad vols and keep snapshots

use flex vols and loose snapshots

As you can't mirror from a flex vol to a trad vol, what we wound up doing was ndmpcopying the data, mirroring the tradvol (and snapshots) nightly, and then we cut over to the new box, initializing a second mirror - then when our last snapshot from the trad vol was expired, we destroyed the traditional mirror volume.

Sorry, I was facing the same thing and couldn't come up with a better way of doing it than what I outlined

Subject: Upgrade 270 and keep snapshots for snapmirror

Hello Everyone,

I am trying to upgrade from 6.5 to 7.0.4 and I currently have trad vols. I also have another filer that is hosting my snapmirrors of many trad vols.

My goal is to upgrade both filers to 7.0.4 to take advantage of flexvols.

I want to preserve my snapshots and have those moved as well. So ndmpcopy is out for me.

volcopy preserves my snapshots, but I can't seem to get it to work between trad vols and flex vols.

Is there a way I can do the following:

1. upgrade to 7G source and destination

2. Migrate from trad vol to flex while preserving my snapshots

3. update my snapmirror w/o re-initalizing the mirror.

I don't have Acopia or Neopath either. Are there tools w/in NetAPP that can help me?
