Migration 1st gen to 5N

Hi,
I have a 1st Gen. Drobo attached to a DroboShare. I want to migrate to a Drobo 5N. Is it possible to simply move the drives across or will I have to buy new drives for the 5N and copy the data across?
Thanks for your help!

Take a look at

A migration of the old “disk pack” is not supported. Even if you could migrate the disk pack I would recommend starting with a freshly formatted Drobo 5N so you get ext4 instead of the old ext3.

I moved drives from one drobo to another while moving data (but I would not recommend recommend doing this since the 1st gen Drobo has only single drive redundancy and this way you would be without protection against a drive failure if you start pulling drives from the 1st gen drobo).
