Am I doing this right? (Plex and DrivePool migration)

Heyo

So I started expanding my Nas drive to 12tb (all nvmes, so speed is irrelevant) and installed DrivePool to keep it simple when it comes to downloads and data management (I'm using Windows), but I just wanted to clarify if I'm doing this right please:

1. Create DrivePool with 5 drives.
2. Create Folder structure to accomodate downloads and media.
3. Copy media from the most populated drives to new structure in DrivePool (around 5hrs).
4. Reroute everything within Sonarr/radarr/readarr/lidarr/Plex.

Is there a more efficient way or am I doing this right?

Thanks in advance.
