Beware that ColdFusion 2021 end-of-life (and end of updates) is coming Nov 2025, and your options
What about more recent releases, if you may wonder? CF 2023 (the current latest release) will get updates into 2028 (5 years after it was release). And there's the coming CF 2025 release, currently in pre-release (as I have recently blogged about), which is of course a great sign for the continued vitality of CF.
But this looming deadline for CF2021 is a reminder that as the years roll on, we not only get new versions but we must say good-bye to old ones.
Wondering what you can do? or when CF2023 or CF2025 support will end also? And what's the difference between "core" support and the available "extended" support which Adobe sells? (The extended support plan does NOT provide updates beyond this coming November.) For more on these, including official Adobe documentation that discusses such things, as well as my thoughts on migration, costs, various options to consider, and more, do read on.
If you've not yet heard, Adobe has opened the prerelease program for the next CF version, aka ColdFusion 2025--though referred to by them for now as Project CFNext.
