I'm trying to replace my 10tb parity with a new 14tb (current setup has 2x 10tb parity). I've read through the parity swap procedure below, but am wondering if there's anything different I need to do for a dual partiy setup and still be protected if a drive goes bad during the procedure.

As far as I know. No there is nothing different. Here is an other good step by step guide:

Parity swap is not needed for that, just do a standard replacement.

Thanks I think I got confused. So could I add the new drive, reassign the old parity to a new data drive, and reassign the new drive to parity, then start array?

You technically could, but it would make recovery much more difficult if one of your data drives decided to act up during the parity build.

 

Much safer to do a simple standard replacement of one of the parity drives, let that complete, then add the drive you unassigned back as a data drive.

 

After you have an old parity drive assigned as a data drive, be sure to make a new flash backup and destroy any obsolete copies of the super.dat file that are hanging around in old backups.

No, you can add a new drive and sync parity at the same time.
