CF 2025 Migration Guide

I would like to switch from CF 2016 to CF 2025. I have already installed the developer edition of the latest CF 2025 version.

Could anyone post me a link to a migration guide or/and provide other useful information about the migration steps to do?

 

Thanks for  any help!

    PS: I can verify that backups have been created for some of the neo-*.xml files, e.g. for neo-datasource.xml, but there have not been been any changes to these files, so the settings from the files in the cf2016settings folder have not been applied.


    Since the migration wizard did not work, I had to export the server settings from CF2016 as as CAR file (as described in the CF2025 Migration Guide).

    When importing the CAR file in CF2025, I had to add a deploypath in pathfilter.json

    {
        "comments": "paths should be semi-colon seperated. To Allow a file: {path-of-file}; To Allow a directory & files in it: {path-to-directory}/*; To Allow a directory & sub-directories: {path-to-directory}/**; To Block a file: !{path-of-file}; To Block a directory & sub-directories: !{path-to-directory}/**; Precedence decreases from left to right. Suppose directory A has directory B & C inside it.To Allow B & Block C: !A/C/*;A/**;",
            
        "bytecodeexecutionpaths": "",
            
        "schedulerexecutionpaths": "",
    
        "car": {
            "deploypath": "C:\\ColdFusion2025\\cf2016settings.car",
            "associatedfiles": ""
        }
    }

    and disable popup blocker for the CF2025 administration site to make the import work.

    Hi Abhishek,

     

    thank you for the link to the migration guide. I have chosen the GUI-mode installation with a different port 8501, since I would like to run the new CF version alongside with the old one. But now I am stuck in step 8 because no CF Migration wizard appears as described. I can login into the administration console but I don't find a migration wizard here as well. Can you help me?

    I have also tried to manually start the migration wizard by following the "Updating from an earlier version" instructions on this website
    https://helpx.adobe.com/de/coldfusion/installing/installing-the-server-configuration.html

     

    but again, no migration wizard is coming up.
