Hello, Is the application deployed as a war file? My workflow is to unzip the new tomcat next to the old one. Afterwards I compare the config-files and jar-files which might have been added for the application. Differences in config-files and jar-files might related to changes in tomcat or to manual configuration for the application.
Also check NTFS permissions of the folder and compare them. After everything is checked, I use regedit to change the service configuration, e.g. for 64 bit Tomcat: Computer\HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\<service name> Computer\HKEY_LOCAL_MACHINE\SOFTWARE\WOW6432Node\Apache Software Foundation\Procrun 2.0\<service name> (stop old tomcat, check the above registry paths and entries, start new tomcat) The effort to upgrade heavily depends on how many manual configuration was done on tomcat in order to run the application. Best method is to reduce changes in tomcat folders and move it to the application side, if possible.

Hope you all are doing well. I am actually new to tomcat. I had required from the client that we need to upgrade tomcat from 8.5.23 to 8.5.75 where there is an application is deployed which makes sap 4.6c integration. So I need to upgrade from old version to new version without losing any data/connections. I couldn't find the steps or proper tutorials on how to start upgrade. Should I need uninstall current version and then install new version and deploy the application? Is there any better way that I can upgrade the current folder structure to new version without uninstalling in thatcase what are changes I need to do? Please let me know. I would be eagerly waiting for the response from you. Thanks and Regards, Meka Rakesh.
