Slide Prep:
Converting Existing Slides

• Download the PowerPoint template version of the style you choose (e.g.: blue.dot) in a directory of your choice.

• Open your existing PowerPoint presentation.

• Click: "Format", "Apply Design".

• Click on the template you have chosen.

• Click "Apply".

• Check that all the changes were done correctly.

Note:
Any already made slide that does not conform to the predefined template as laid out by PowerPoint will not convert correctly to that template. This is deliberate: PowerPoint assumes that when you deviate from their provided "AutoLayout" style you do so intentionally and do not want any global change to happen on that particular slide. Slides that do not appear to have converted correctly can mostly be corrected by clicking "Slide Layout" and "Reapply", you will lose intentional changes, e.g. font color change within a sentence, etc.
