Upgrading hdd size + converting to XFS

[Ryvius]

Here is my current setting up:

 

1 X parity 3tb

3 X data 3tb

1 X data 2tb

 

I am looking to add a 4tb data drive, a cache drive, replacing the parity drive with a 6tb, and convert the old parity to another data drive. In the process, I am looking to convert the file system to XFS. I am planning to take the parity drive offline, then format the new 4tb into xfs and just copy the files directly from one of the 3tb on to it, then reformat the 3tb to xfs and copy another drive on to it until all the drives are converted. I will then install the 6tb as parity and reformat the old parity for data. Would this be the best way to do the conversion? Thanks

Might want to use rsync to copy the files so that it does a compare to ensure that everything copies properly from disk to disk. Your approach is sound, although your array is unprotected.
