In the CRW 2.0 end user guide, there's a section on how to convert a Che 6 / CRW 1.2 workspace to a Che 7 / CRW 2.0 devfile.

This is fine.

https://access.redhat.com/documentation/en-us/red_hat_codeready_workspaces/2.0/html-single/end-user_guide/index#converting-a-codeready-workspaces-1.2-workspace-to-a-codeready-workspaces-2.0-devfile

But in the 2.1 docs, this becomes "converting a 2.0 workspace to a 2.1 devfile... when BOTH releases use devfile and there's no conversion required because they're also both based on Che 7.

https://access.redhat.com/documentation/en-us/red_hat_codeready_workspaces/2.1/html-single/end-user_guide/index#converting-a-codeready-workspaces-2.0-workspace-to-a-codeready-workspaces-2.1-devfile

So... this whole section makes no sense and should be removed completely, since support for CRW 1.2 is now EOL.
