RN428 new array help

My RN428 has all 8 bays filled with 10TB drives running as raid 6. I purchased 8 14TB drives to replace the 10TB drives. I backed up all of the data to external drives. I would like to power...

I would like to power down the system and replace all of the drives with the new, blank 14TB ones. I am afraid that if I do this, the system will still have the information about the previous 10TB drives volume

There is a small OS partition on the disks, that contains the Linux OS, the ReadyNAS application, and the configuratoin.

So removing the old disks is all you need to do. The system will do a factory install on the new drives when you power up.

Thanks for your reply.

I guess that i have a small addtional wrinkle...

I have the 5 drive chassis expansion added with an additional volume. I will not be replacing those drives and want to still keep that volume. Can i still just replace the drives in the main chassis without any issues?

  You will need to EXPORT the EDA500 volume, then re-configure the NAS, then import the EDA500 volume. Import is an automatic function at power-up so long as the volume has been exported. So once exported, disconnect the EDA500 before you again power up the NAS. Once all is ready for the import, just connect it again with power off and power up.

    Please look this over and see if i have it right:
    
    1. Export the volume in my EDA500 (even though it is scary and says that I am destroying it)
    2. Power down the RN428 and EDA500
    3. Disconnect the EDA500
    4. Remove the 8 drives from the primary RN428 bays
    5. Replace with 8 new 14TB drives in primary bays
    6. Reconnect the EDA500
    7. Turn on EDA500 and RN428
    8. Configure new Volume of new 8 14TB drives in primary bays
    
    The existing volume in the EDA500 should reimport itself correctly automatically and I should have a new RAID 6 volume of the 8 14TB drives in the primary bays.
