Yes. The transition from Xamarin to Maui has been similar to transition from .net framework to .net core.
A few things you will run into:
- namespaces have changed
- certain things will be deprecated but still currently work (ie FillAndExpand)
- platform specific setup has changed (you'll need to convert to the new way, but code will likely remain the same)
- upgrade your nuget packages to the Maui equivalents (the ones we used had Maui versions so we didn't have to change any of them)
- certain ways of doing things have change slightly, like how to run things on the main UI thread (you'll see warnings)
- your xaml code will remain mostly unchanged but your layout may need to be fixed (especially if your dependencies changed their interfaces)
That's all I can think of right now. There's no easy way to do it and it's going to suck. Focus on getting it to build with all your dependencies upgraded and then go from there.
