eespin, Honestly the best approach for moving SnapLock data to SmartLock (and yes I'm biased here, but I'll qualify it), is to use DobiMiner.  I could spend an hour writing up why exactly, but I already did in a blog post about 4 months ago that you can read here: [URL] I even went to the extent in that post to record an actual NetApp SnapLock to Isilon SmartLock WORM migration.  It's only about 7 minutes, long; apologies in advance for having to listen to me for 7 minutes if you watch it [IMAGE].  You don't want to use isi_vol_copy (or any other ndmp-based mechanism) to move data like this, especially if you are keeping this data around because it's under SEC 17a4 or some other regulatory retention requirement, because you'll never get proper chain of custody, which we provide in every WORM migration as illustrated in the demo.  I'm happy to discuss it more if you'd like, just drop me a line:  -Chris Klosterman Principal SE Datadobi chris.klosterman[NAME].com
Hello everyone, We are looking to migrate our current Netapp arrays over to Isilon, however there is some concern with corruption as well as what the best methodology would be for performing this migration. We have an environment that relies on the Netapp Arrays for it's snaplock technology (Filenet, out of the box no extra modules) and files that are written (well moved into) snaplock shares are also entries in a concurrent database. If it any point the two get out of sync there is corruption. To add some extra anxiety to the migration there is no good backup of this data (one of the reasons we are migrating) there is a mirror but it's LAG time is almost a 3 months.   My questions would be: What is the best way to transfer all the files (looking for a tool, or functionality in Isilon maybe)?  How do I preserve retention during this transfer (don't want 3 year old files with 7 year retentions, starting over and be retained for 10)?  Any issues with corruption?  Anyway Isilon can be a target for a VSM (Volume Snap Mirror), that is have the Netapp NAS replicate/mirror to Isilon (longshot I know lol)?    Sorry for all the questions am just desperate for some good info.
