Upgrade / Backup / Restore Pro6 and 316
Hi team, So i managed to find myself a brand new 316 ReadyNAS.. I have an existing Pro6 with 6 x 3TB disks installed with XRAID-2: but I made it so that 3 are used for capacity and the other 3 a...

Looks like you did that before you captured mdconfig. A bit risky, if it had been in RAID-10 you could have killed your volume.
However, the RAID mode is 6, so you didn't have triple redundancy (and that is confirmed by the NAS telling you the volume is unprotected).
The sector count on md2 looks low - is there an md3? What disks are you using?
As far as next steps, I suggest putting the two removed drives temporarily into the RN316 as jbod (using flexraid). The simplest way is to put one in first, do the factory install, switch to flexraid, then hot-insert the second. You should then be able to create a second volume. If you have any unused disks, you could try adding them in as additional jbod volumes.
Make sure snapshots are off and bitrot protection are turned off for each share, and migrate as much data as you can. Keep fullness below 90% If everything doesn't fit, you will need to store the rest on a PC or external drives.
When all is copied, reset the pro, use normal xraid, and copy back from each jbod volume (leaving the original install disk for last). Then hot-insert the two removed drives (one at a time, waiting for expansion to complete).
If you have interest in expanding the pro later on, you can look into switching it over to OS6 now. Since you are resetting anyway, it is the right time to switch (if you want to). It is unsupported by Netgear, but it would allow expansion to larger drives later on.
Yes, exactly.

Thanks for your replies.
What I will have to do then is borrow a 5TB ext HDD from a friend, transfer a folder with 4TB onto that then as you suggested - move the remaining data onto the 316 with 2 of my drives in it.
I am interested in changing the Pro to OS 6. I really don't know much about it though.
My main concern is being able to migrate my addons to the new OS. Is there an easy / simple way to save their data and add it back to OS 6?
The two main apps whos integrity I don't want to loose are Plex and transmission. Any advise on this?
They are both available on OS6, but the binaries are built for the OS. I suggest that you ask for advice on the plex and transmission forums.
On migrating the pro to os6 - perhaps wait until you get the RN316 up and running, and then decide. You'll have more experience with it then.
