Heat Maps are good way to depict the application roadmap. A quick way is to show the current state of architecture on the first slide of ppt. And add another slide for the target state. And in between the two slides of Current and Target state, it is possible to add migration steps(phases).
Few legend to add on the heat maps for the application roadmap can be - Consolidate, Decommission, New and Impacted. I have tried it with the portfolio for one Line of Business and its provides the clear direction for future state aligned with business vision.
