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 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 and i will have to somehow create a cludge to clear the old data and create the new.

Should i first kill the old volume, then power down, replace the drives and power up? If i do that, will the original drives ever be usable again in the same array or will the data/volume info be killed on the drives? I may want to save the drives as a backup.

What is the best way to proceed?

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.
