Successful Celerra to Isilon Migrations?

Question

Has anyone had a successful migration from Celerra's to Isilon?  I'm sure there has been, but I'm curious as to the method used to migrate.

I migrated 284TB from Celerra NS80 to Isilon, long migration using emcopy and rsync.

It should be noted though that there was a bug when using emcopy that was only recently fixed in the latest v6.5.5.14 OneFS code (bug was in OneFS and not emcopy). As noted in the v6.5.5.14 release notes:

I also searched the release notes for v7.0.1.2 and don't see mention of the fix, so I'm fairly certain the fix isn't yet in the Mavericks release. It was an issue on at least the initial release of Mavericks. I could be wrong though and would need someone else to confirm (and maybe it simply didn't make the release notes)?

Just something to keep in mind.

that bug will drive you bonkers when you are trying to figure out what you are doing wrong with emcopy where in fact it's not the culprit. For some of my migrations i have used robocopy on a Windows 2008 R2 box where robocopy supports multiple threads. One thing to note is that when i initially started my migration i would get a lot of permission errors, ACLs from Celerra would not propagate to Isilon even though i had Full rights on source and target. One way to fix that was to grant my account "root" permissions on the share.

The EMCopy bug is not fixed in 7.0.1.2.  It should make it into 7.0.1.3 I believe.
