I haven't done the best job of promoting some of the content that I create with my partners at Algiz Technology. Recently, I worked on a pretty in depth series of blog posts on the top of Windows 10 migration planning.
The first part of the series covers what I feel are some essential topics you need to cover when planning your migration. You shouldn't start until you have made some decisions, defined your minimal viable product and the scope of your project. I give some insight on some directions you may go and some products you should consider.
The second part of the series covers cover application readiness, which is a topic near and dear to my heart! Inevitably, applications are the most time consuming complex part of any desktop migration.
I hope you enjoy the series!
