Old HD as new ... Migrating Hds

I recently migrated my Data from a Zyxel NAS to a System with OMV. The Raid1 Arrays are duplicated and backed up.

My Problem: In the Zyxel NAS are the much newer HDDs (3-4 Weeks new). How do I have to smuggle the the newer HDs from the old Zyxel over to the OMV-RAID?

My Plan:

1. Tear appart the old Raid
2. Renew the HDs
3. Exchange the HDs in the OMV-RAID with renewed HDs, one after the other

Will this working? How do I have to "renew" the "new old" HDs?

No ideas?

I think i want erase them secure and deleting the partitions ... new enough?

The point is:I'm wondering what I have to do, that the Array (than degraded) akzept the "renewed" HD as a new Twin.

Bye, Micha
