I made a series of blog posts going through the #MSDyn365FO upgrade process from 7.x to 8.+ this week, aiming at the ones who perhaps have less complex upgrade scenarios. I realize some have overlayerings and tons of customizations they need to get ready through a code upgrade process, but maybe my posts can inspire still. Having to manually service the 7.x the next few months, until we all go #evergreen #OneVersion can be avoided if your application and organization is ready to get on 8.+. Take a look and let me know what you think.
