QNAP question, expanding single drive to RAID 5 volume

[ChrisD.]

Hi, I will be migrating data from a Synology NAS to a QNAP NAS.

Synology has four 6TB drives in SHR (RAID 5).

QNAP is a 6 bay device.

I've backed up about 50% of the Synology, but I've run out of drives. To save me buying another 4TB or larger drive after work, could I break the RAID (at risk, obviously) in the Synology, insert one single disk into the QNAP and copy the remaining data over. Once copied I'll slowly expand the QNAP to 4 drives in RAID 5. I've had a quick read online and I think it's possible, just wondering if there's any gothya's, ie file system 32 bit limits etc.

Thanks!

I would try and avoid doing that

On my qnap I had 4 x 1TB raid5 , I was going to go to 4 x 1.5TB raid 5
I backup up my data to another PC then tried to upgrade , it went boobies skyward

Ended up just removing the 4 x 1TB stick in the 4 x 1.5TB and creating a raid5 set-up and copying the data back from the PC
