Replace ReadyNAS RND4000v2 with new 214 or similar
My ReadyNAS is now 8 years old and I feel it is time to replace it probably with an RN214 If I buy the new NAS with 1 drive and copy the data on to the new drive can I then take the old disks out...

To be clear on this - you will lose the data from the old disks.
If your disks are old, then you might instead consider starting fresh with new disks. It's generally more cost effective to start with fewer but larger ones, so you can expand into empty slots. One benefit of getting new disks is that you can use your existing NAS as a backup - scheduling automatic daily backups from the new one. I use my own older NAS that way, and it works quite well.
I just want to re-iterate what Marc_V said, that the new drive cannot be larger than the old drives you are re-using if you want them all to form a single RAID volume in the end. Drives added after initial set-up must be as large or larger than the original. You could, after switching to FlexRAID, make the two old drives a separate volume if they are smaller.

Yes - I should have pointed that out in my reply. If you go with new larger disks, you won't be able to add your existing disks to the same volume. So get the same size as the smallest drive you want to reuse; but consider larger/fewer disks if you want to start fresh.
OS-6 is more flexible than older ReadyNAS as far as flexraid goes - you can switch to flexraid at any time w/o data loss.
Thanks all for your contributions. The existing NAS, being rather old, contained 2 x 1GB and 1 x 2GB. Not a lot.
Have decided to go for two new 4GB disks.

I recommend NAS-purposed or Enterprise disks. Many desktop drives are shifting to SMR, which is not a good technology for RAID.
Seagate Ironwolf or the older WD40EFRX are good NAS-purposed choices. The newer WD40EFAX is also SMR, and I recommend avoiding that one.
