Yes, you can create another RAID1 with new 10TB drives. You will then gen this theoretical 14TB space.When you want to upgrade old 4TB drives, just replace one of them and let the rebuild to finish. Then replace another one and you will have new capacity available on the primary RAID with all data on the new media.If you want to create a RAID5 then copy data from secondary RAID to a new bigger primary RAID. Delete secondary RAID. And add choose an option to migrate from RAID1 to RAID5 using additional 2 drives.I hope this helps.
