Can I open runs created in older versions of TNM in the most recent version of TNM?
Any run created using older versions of TNM (e.g., Versions 1.0, 1.0a, 1.0b, and 1.1) can be opened in TNM 2.0 and above. TNM 2.0 (and above) will ask you if you would like a backup copy of the run automatically saved during the opening process. If you do not save a backup copy of the run, a run opened by TNM 2.0 (and above) will be permanently converted and will not be able to be opened in previous versions of TNM.
