When upgrading to a new version of Delphi, compiling and installing all the packages can be the hardest part. These can include Third-party (purchased and free) components, and in-house developed components. This is an example of updating a third-party spelling component set to Delphi 11. This package was quite easy, others were not so. I did no rehearsal for this video, and it's working with production code.  Enjoy the video on YouTube.
