Steps I did before upgrade

stop ColdFusion stop apache2

apt-get update apt-get upgrade

do-release-upgrade

during upgrade get pop up saying about smb point modification I selected the "keep the existing config file for samba points "

I troubleshoot and check all the files which are causing the problem but no luck can some one tell me exactly where to look

Answer 1

ColdFusion MX (version 6) reached its end of life around 15 years ago. JRun is long dead. That Apache connector (mod_jrun22.so) will not run on the upgraded versions of Ubuntu and Apache. I hope that's a dev server you've upgraded, not a production server. You're stuck on the old operating system and web server versions unless you can also upgrade to the latest version of ColdFusion. If that's a public-facing application, it's a massive security risk to stay on CFMX 6.1.

Alternatively, you can try running your application on https://www.lucee.org/, an open-source CFML application server. Unless you have some CFX custom tags or other old school libraries, you should be able to at least test the application pretty quickly.
