Upgrading from an old version of the AR Magic Bar takes about 2 minutes.
IMPORTANT: Although upgrading is a straightforward process, I would not advice to do it in a full on ongoing project without a proper back-up. As the AR Magic Bar is still evolving a lot, some errors could occur. Please do a full back-up of your project before upgrading.
Import the AR Magic Bar (Pro) from your package manager
Delete the script TransformLogic.cs in the shown folder
Open up the prefab and image editor and (if necessary) drag in the placeable object database from the PlaceableObjectDatabase folder
Do a quick double click on recreate objects button (right bottom corner)
Remove the old AR Magic Bar Asset from the scene and drag in the new one (Magic Bar Pro)
Drag the placeable object database into the AR Magic Bar
DONE :)
