Double click the "mcrconvert-[version].jar" file to open the program. Select the source MCreator workspace .mcr file using the "..." button. Repeat the process for the destination folder. Make sure the folder is empty (the converter doesn't allow you to use an already populated folder to prevent data loss). Now click the convert button.
When importing workspaces from MCreator versions older than 1.7.9, Events, Global events, Overlay conditions and Mob AI tasks will not be imported.
For versions older than 1.8.2, you will be prompted to name your workspace, write the description etc., much like you do when creating a new workspace in newer versions of MCreator.
If the conversion was successful, a dialog opens giving you the option to either convert another workspace or exit the program.
