Hi guys,I am increasingly running out of space on my old Duo and there isn't any way to expand this device any further (or not that I am aware of).If I bought an NV+ 2 or maybe something bigger....could I simply pop in my old drives from the Duo and expect it to continue functioning as normal?If not, what would the procedure be to transfer the data?Graham

While you can simply "pop in your old drives" into an NV+ v1, you cannot do so with an NV+ v2. There are currently three families of ReadyNAS units in existence. The three are differentiated by the processor. The original family that started in 2004 ended with the end of production with the NV+ v1 and Duo v1. This family has the Infrant Sparc processors. (Infrant was the originator of the ReadyNAS units). The second family are those powered by Intel x-86 chips and are referred to as x-86 units. This family started with the original Pro (6 bay unit) and followed with the NVX (4 bay unit). These units have been discontinued by were replaced by newer updated x-86 based units, the Ultra, Ultra Plus and Pro series and each series has a 2, 4, and 6 bay model. The third family is the newest and is based on Marvell's ARM processor and includes the Duo v2 and NV+ v2. You cannot simply move the drives from one family to another without the new host completely wiping the drives of all data and reformatting. Nor, can you move them to another brand for the same reason. Depending on how much data you have, you could purchase one drive for the NV+ v2, copy your data over and then add your old drives to expand the array. However, this is somewhat risky for if there is a problem, all of your data is in one location. Another way would be to not only purchase the new drive for the NV+ v2, but also to back up the data before you did remove the drives from the Duo. Before moving the old drives to the NV+ v2, you should check to make sure the drives are on the Hardware Compatibility List (HCL) for the NV+ v2. If they are not, then you will have to purchase all new drives for the NV+ v2. However, you could then use the Duo as a backup target for the NV+. NAS to NAS backup is the fastest way to do a backup and can be scheduled so you don't have to worry about it.

But surely one could do a semi-destructive transfer...?I'm thinking of upgrading from a Duo v1 to a Duo v2, mainly because it is becoming obvious that support (read: interest) for the sparc device is disappearing. I have been thinking of the upgrade mechanics as well. I have 2 disks running in X-Raid. Mirrored.I'd have thought that you could:1) Remove drive 2 from the Duo, and thus render it as a single-drive file server.2) Put drive 2 in as drive 1 of the Duo v2. It would be formatted, and empty.3) Perform a complete copy from the Duo v1 to the Duo v24) Turn off the Duo v1, and pull out disk 15) Put the disk in as disk 2 of the Duo v2. This should format it, and then begin to synch the two disks until they are mirrored again...No? If you do that over 24-48 hours your period of risk is small. On top of that if you in fact have an off-site backup (as I do) you could do the file copy from the off-site disk into the Duo v2 before switching it off...

Quick question....I'm in the process of upgrading from a Duo v1 to an Ultra RNDU2000. I am playing it conservatively and performing a backup to an external hard drive through the front USB port before I migrate disks to the new NAS Ultra. But the backup has been running for over 3 days now! :? How long does it take to backup 540GB of data on a 1TB disk?!? :(

What filesystem is on the external USB disk? EXT3/FAT32/NTFS/something else?

Possible?: Upgrading from Duo v1 to NV+ v2

That is odd. EXT3 should be faster than FAT32. Also FAT32 has a 4GB limit per file.

OK, the USB backups kept failing and I got fed up that method all together. I decided to connect the new ReadyNAS Ultra 2 to my network and see if a NAS-2-NAS backup would fair better. I purchased a copy of your guide (very nicely written, by the way!) and set up the backup jobs as you described. They are running as I type this, but the guide never spoke about migrating the drives after the backup completes. Allow me to explain....

My old ReadyNAS is a Sparc Duo and the new ReadyNAS is a x86 Ultra 2. I have 2x1TB drives in the Duo and a spare 1TB drive (for backups). Here is the plan I was hoping to follow....

1) Install the spare drive into the Ultra 2
2) Copy my files from the Duo to the Ultra 2
3) Remove one drive from the Duo and install it into the Ultra 2
4) Mirror the drives in the Ultra 2 and let them sync up
5) Remove the second drive from the Duo and keep it in a safe place as a backup

Is this possible?

Yes, though it is best if the Duo drives are also on the ultra HCL. If you like, you can delete the partitions (by connecting the drives to a PC) as you move them to the Ultra - that ensures that the ultra will see them as new.

I didn't discuss that I guess as I believe it's best to use new drives in a new unit however as StephenB mentioned provided the disks are on the compatibility list (http://www.readynas.com/hard_disk_hcl) for your new ReadyNAS that should be fine.
