When you upgrade your legacy Rhino to a current version, the new version may not be support some of your plugins, add-ons, scripts, output devices like laser cutters and more.

For example, users with older laser cutters that could print to the device directly out of Rhino 5 installed on Windows 7, found that the same Rhino 5 installed Windows 10 could not do this.

For Rhino 7 or later, you will need a new computer that runs Windows 10 or later for optimum performance.

While the older Rhino 4 or 5 software will not run well on your new computer, your newer Rhino 7 or later software will also not run well on your older hardware. This is why you need to keep both computers.

1. Keep Rhino 5 on your old computer.
2. From Rhino 7, use the SaveAs command to save your files in the Rhino 5 3DM file format. (To access the SaveAs command on the Mac, go up to File menu and hold down the Options key.)
3. Copy this file to your legacy computer.
4. Open in Rhino 5.

If you require access to your Rhino 6 after you have upgraded, you will need to licence your Rhino 6 with the CloudZoo method. You will then be able to continue using Rhino 6, even after you have upgrade to a Rhino 7 or later.

Note: You will be allowed to run both on the same computer, However, you can not run Rhino 6 on one computer, while running Rhino 7 on another.

1. Keep Rhino 6 installed on your computer.
2. From Rhino 7, use the SaveAs command to save your files in the Rhino 6 3DM file format. (To access the SaveAs command on the Mac, go up to File menu and hold down the Options key.)
3. Copy the 3DM file to your legacy computer, if required.
4. Open 3DM in Rhino 6.
