Migrating ReadyNAS Duo to RN102
It's been a while. Sigh. So, my trusty old sparc box needed an update - it's still going strong but is just too slow by today's standards so I bought a RN10200 and a couple of Seagate 2Tb (yes I'm on a budget).
I imagined I could just have both on the LAN and do a backup pull from my shares to the newly powered-up NAS. But now it's settled down I see the layout of the shares is very different. Beofe I had just two shares, backup and media. The new NAS has separate shares for docs, music, pictures etc. - separate shares that were all just folders in the one media share before.
So what should I do? I was aiming at using backup so it would be direct NFS transfer from one box to the other... I suppose I could create a new folder "media" and ignore or delete the other shares - or would it be advisable just to drag&drop copy into the new shares from a PC?
It's a bit faster to reorganize on the duo, and then do share-by-share backup to the RN102. Shares are subvolumes on the RN102, so moves between shares become copy/deletes. Also if snapshots are enabled, they also can start taking up space.
So maybe create the folders on the duo that you ultimately want, then access the duo's C volume (\\nasip\C with NAS admin credentials), and shuffle the files around. Then use share-by-share backups to get them onto the RN102. Drag/drop works, but all the data is copied through the PC.

You should align the shares on the two systems - if the duo shares are working out for you, then just delete the ones on the RN102 that don't match, and create any new ones you need.
Also if you have set permissions on the duo, you should probably set up matching user/groups (with matching uid/gid) on the NAS. nobody/nogroup is a bit of a problem because the guest account\groups can't be matched. I just set owner/group to admin/admin on the duo side myself.
I used rsync for data migration. If you set up the backup jobs on the duo, then start with incremental NFS, run them, and then edit them to use rsync. Then run them again. The second time will be quite fast.
After you've migrated, I suggest using the duo as a backup (reversing source/destination on the backup jobs)
Thanks, I suppose the new structure makes better sense from the permissions and services pov but I will just migrate the one share as you suggest for now. If I did want to move all my Music, for example, into the music share after I've got it backup copied into the media share on my RN102, is there any better way than just dragging and dropping from folder to folder?
