Recently someone asked me for help moving from ArcMap to Pro, so I solicited colleagues at Esri for information and useful links. I totally understand the challenge. If you're like me, when you just have to get something done your go-to app just still might be ArcMap. It's a powerful, dependable, and capable desktop GIS, that will live on for a very long time. But there's plenty of reasons to migrate to Pro now.
You bet it takes a bit of time and relearning, and perhaps leaving the comfort of your existing workflows and well-worn workpaths. But the benefits are large, with many new features and capabilities―not to mention online integration. All of these make it a must-learn for every GIS professional.
While I can admit that I'll still be cranking up ArcMap often for well-worn workflows, I will also admit that I'm trying hard to find the time to relearn existing workflows in Pro, and learn new ones. And when I do, I'm pleasantly surprised. And the comments I get from the many users I interact with underscore the same, and that it's time to let go of the security of the ArcMap blankie...
