Hello
Unfortunately, there isn’t a way to upgrade NASware on a WD Red drive. In our testing we did not find any issues mixing both NASware 2.0 and 3.0 in the same environment. However, you may want to verify with your enclosure/controller manufacturer to verify compatibility with their hardware.
We are no longer producing NASware 2.0 drives, so there shouldn’t be a lot left on the market. In addition, all 5TB and 6TB drives have only been manufactured with NASware 3.0.
