Well you can migrate from single disk to a RAID 1 but then you would be forced to have the 2 TB disk still in there as removing it would render you a degraded disk volume. Furthermore you would only be able to use 2 TB of the 3 TB available on the larger disk.
This is what I think is easiest:
1. Power down the NAS.
2. Reinitialize the NAS from scratch with the 3 TB disk.
3. Connect the 2 TB externally via USB or eSATA. It should appear as multiple disks and you should be able to find your data in the largest one of them.
4. Login as admin and use
Web File Manager to copy the data to the internal disk.
This procedure is by no means totally risk free so make sure you have backed all important files up before starting.
No, RAID has never ever been a replacement for backups. Without backups you will eventually lose data!
