Its not possible to migrate from CF8 to CF2018. You can migrate from CF8 to CF10 and then CF10 to CF2018, as a workaround.

I don't know why Anit is saying it's "not possible" to update from 8 to 2018. It's certainly "possible". I have 2 current clients who've just made the move. Of course it's a little more work than moving from 9--which is itself a bigger jump than from 10.  A move from 10 or above is easier. Of course, some migrations are far easier than others. Just depends on the coding used. I suppose Anit may be referring to what the migration guide covers, and fair enough. I just wanted to clarify things, as I don't see any particular reason why one MUST update to 10 first. Finally, I'll say that I and others can help folks making that move. See my list of troubleshooting consultants at https://www.cf411.com/cftrouble. (I see that two people asked about 8, and Anit a has answered them each individually with the same answer. As I wanted to offer a counterpoint (to both), I'm posting this as a new comment rather than duplicating a reply to each.)

One gotcha that just got me is with cflogin when moving from CF10 to 2018. In CF 8, 9, and 10 this worked great: Main (root) Application.cfc just used to authenticate via cflogin and set an ApplicationToken e.g. RootToken. Different applications in sub-folders that required a login had their own Application.cfc with different application names but with <cflogin applicationtoken="RootToken" >.  This gave my server a single sign on (SSO) without any extra application overhead between sub-applications within my site. Once I upgraded to 2018, none of these sub-applications worked because the user was not logged in.  I tried "extending" the Application.cfc files and using an ApplicationProxy file, but that didn't work. Eventually, I just renamed all my sub-applications to the same name, which made the whole site one big application and that worked.  I liked the old way better though.  I also don't understand what the point of the ApplicationToken attribute for cflogin is now. Hopefully this will keep someone else from beating their head against a wall for too long...
