The way I suggest is to do this: First Time
1. Install new version side-by-side. 2. Separate CATALINA_BASE and CATALUNA_HOME. 3. Create a symbolic link for CATALINA_HOME. 4. Make the necessary changes to config files, make sure the CATALINA_BASE lib only contains the jar files for your application. Keep all NATIVE jars in CATALINA_HOME lib. 5. Make necessary updates to registry as needed. 6. Stop service. 7. Start service. Future times. 1. Install new binaries. 2. Update symbolic link for CATALINA_HOME to point to new releases. 3. Stop service. 4. Start service. Note: may have to stop service before you can modify the sym-link. Hope this helps.

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.
