I am considering purchasing a n5200 pro and have a question.

Initially, I plan to have 2 drives @ 1TB each in a raid 1. When it is almost full, my plan is to add 3 additional drives @ 1TB each and build them into a raid 5. When the raid 5 is built, I would copy the information from the raid 1 to the raid 5. After the copy is complete, I would like to expand the raid 5 by adding the disks from the raid 1 to it (creating a large 5 disk, 4TB usable space raid 5 array). Is it possible to do this without data loss?

Any assistance will be appreciated.

Thanks in advance!
