Thank you for your clear answer, but I think I didn't started the thread clearly. I had onbord the 6 wd red of 3Tb each with the two shares on it. I made a copy of one share and thinking that was all I did the upgrade loosing all the data in the second share. The right question shuld be: Is there an yway to recover them?
Well, it depends on exactly what you did.
If you removed the 6x3TB drives, installed one or more of the 8 TB drives, and then converted to OS-6, then your original array is intact. If that's the case, you could mount the original array as read-only. Just power down the NAS, remove the new drives (labeling by slot), and reinsert the original disks (ideally in their original order). Then power up. When done backing up the data, power down and reinsert your new disks.
But if you did the conversion with the 6x3TB drives in place, then the conversion process would have reformatted the drives, created a different partition structure, and then installed a new file system on the data volume. If you are really desperate to get the data back, you could try Netgear's data recovery software (or RAID recovery software on a PC), but if you did the conversion with the original disks in place I think the odds are very poor - especially if you have copied back some files to the new data volume.
If you put the new drives in before you changed to OS6, and you still have the old drives (preferably marked as to location they go in), you could put in a spare drive, revert the chassis to 4.2.x and then install the old drives (with power off).
If you don't remember the order of the drives and have an old log .zip file, you can find out which serial number goes where in disk_smart.log.
Once you have the data you need, use the spare drive to move back to 6.x and then put your new drives back in (again, with power off).

Thank you again, unluckily it is the secon scenario you described, I will try with raid recovery but as you said I know I have very very few chance.
I think you answerd and this is the conclusion!

Back again, sorry, even if, as you said, I have very few chance I would like to try a round with a recovery sw. My problem now is how to make the nas "visible" to the sw, because I downladed a few trials for raid recovery but none of them see the smb share.
Thanks

Recovery requires direct access to the file system - so the software can't recover from SMB.
You need to power down the NAS, remove the drives, and connect them to the PC. Likely you don't have enough SATA ports - if so you will need USB adapters/docks.
