Upgrade of Tomcat server

For security reasons, I have to upgrade a Tomcat web server on Windows Server 2008 that I haven't configured myself. It is Tomcat 6.0 and I have installed Tomcat 7.0 side by side with the Tomcat 6.0 installation, then renamed the Tomcat 7.0 service to the same name ("Apache Tomcat") as the 6.0 service and copied the webapps subfolder to the 7.0 folder. But the web application doesn't work with Tomcat 7.0. What more should I do to make it work under 7.0? I can still make it work, when I start the 6.0 service.

You can make test run in unzipped copy of tomcat 8+java8 on desktop machine.
Just add war files in webapps/
Run startup.cmd
Then check logs/catalina.out on what happens.
You can post catalina.out from single startup if you need help with interpreting errors.

That's not a lot of info to work with. What doesn't work? What error message do you get? What does the logs say?

I couldn't find any error message in the log, I have a feeling that the some more configuation needs to be done to make it work. I don't know so much about Tomcat, how can I see what web applications are currently deployed?

I found out that the SSL configuration in server.xml was not copied over to Tomcat 7.0. Thanks for all feedback.

Try to add some markings around customizations you do in config file, for next migration to go easier...
