Coldfusion upgrade 9 to 11

I've posted on this before.
I'm running CF 9 on Windows 2008.
I need to upgrade to CF 11.
I've installed CF 11 (as server install) to not co-exist with CF 9.
Once I'm done and the migration agent works, the site is still running under CF 9 though the CF Administrator seems to be running at CF 11, or at least part of it.
If I stop the CF 9 service I'm not getting anything any longer.
There must be some file(s) I need to move, but I can't figure out what they would be.
Has any one done this before -- update CF 9 with CF 11?
This is driving me nuts. I've been on it for two weeks now on and off.
I'm trying to figure out how Coldfusion links up to my site. In other words, where do the CF 9 files link up to my site to run it? If I can figure that out, I'm guess I can figure out where the problem is.
I checked in IIS/Handlers and I see many Handlers for both CF 9 (links back to CF 9 files) and a few for CF 11. I'm wondering if I should just delete all of these CF 9 handlers -- or if that will just make matters worse?

You are correct that your problem exists in IIS.  You should remove all references to the old version.   Step 1 should have been uninstall ColdFusion 9 and go through IIS/Handlers and make sure you delete any references to that old version.  

We had a similar problem.  This article address problems we encounter and the fixes.

Charlie Arehart has several articles on how to verify you have properly removed phantom references and reset the web connectors.

first of all, you should always use one cf server with iss, if you plan to use cf11, you should either change your mappings to point to the sites in the wwwroot folder and install the cf11 server as standalone, so you can run two version seperately bt files residing only on one place
