Hey Bruce,
Sometimes you just want to put a modern Kendo/JS skin on an otherwise solid, mature, maintained application, which has its own UI, and perhaps even mobile apps, based on a specific MySQL or SQL Server schema, at least as a "bridge" to a long-term solution, but maybe as a part of the long-term solution - it's better to not mess with the schema, so that the default/standard UI of the application, especially the tools you don't want to rewrite, stays usable. I am working in that scenario now.
