Upgrade from Duo (v1)
Yes - I still have a Duo which has worked pretty much flawlessly over the years and even through and upgrade from a 1TB hard drive to a 2TB drive. It's time to upgrade. Money is not a factor. Reli...

I'm in the process of doing this too.
I've gone with a RN316 with 6x WD Red 4TB in RAID6. I missed out on the 6TB drives as they were added to the HCL about a week after I ordered my gear. I figured I would spring for the biggest drives available without excessive cost. 4TB drives should serve me well for a few years. I based my choice on cost per TB and a number of online reviews. I favoured NAS grade drives over desktop drives. Also, having read a number of articles and posts on the issue, I opted to go with a 6 drive RAID6 system as the the parity overhead is only 1/3 instead of 1/2 in a 4 drive unit. The risk of bad sectors increases with the larger drives, so I figured dual redundancy would give an additional layer of protection. I also have a cold spare available on site for immediate replacement should one of the installed drives fail. This should ensure that my array remains redundant while being resynced.
As suggested by others, I have found importing data easiest and quickest by setting up a backup job on the new RN to copy data from the old RN or other NAS using WIndows / NAS timestamp protocol. This method also doesn't require any computer resources to move the data. You can also set up multiple jobs and they will execute one after the other without any further intervention (just hit start).
My 2 RN Duo (V1) have both been rock solid and haven't missed a beat for more than 5 years. I plan to use them and other devices as backup stores for data served from the RN316. At some point in the future, I may add another RN316 as a backup device to provide some hardware redundancy as well.
All the best with making your choice. OS6 provides so much more functionality over OS4.1. There are a few quirky differences that take some getting used to, but generally an enjoyable experience.
