Embedded Files
You can compare changes to the shipped configuration files between versions using the appropriate link for your version... This is important if you have customised any of the configuration files... i.e. you will need to merge in your changes after downloading the new version. If there are no shipped changes you can simply overwrite with your version.
This page assumes Tomcat is installed on a Linux OS under /tomcat using a tarball (i.e. not by using a package manager like yum or apt) and that users/groups have been created, environment has been set, systemd has been configured etc.
Download Tomcat
Download Tomcat
Download latest appropriate version and copy it to /tomcat on your target server.
The Core tar.gz file is recommended
As 'root'...
cd /tomcat
TOMVER=$(ls -t apache-tomcat*.tar.gz | awk -F".tar.gz" '{ print $1 }' | head -1)
OLDVER=$(file /tomcat/latest | awk -F"/" '{ print $5 }' | tr -d '\047')
tar xvf ${TOMVER}.tar.gz -C /tomcat
rm /tomcat/${TOMVER}.tar.gz
chown -R tomcat:tomcat ${TOMVER}
chmod o+x /tomcat/${TOMVER}/bin/
The command for setting the TOMVER variable works best if there are no old tomcat tar.gz files in /tomcat i.e. it needs to return one value. If there are multiple files it picks the first one (assuming you want the most recent).
The command for setting OLDVER assumes you have a symbolic link called /tomcat/latest that points to the current version of Tomcat. If you have installed using the instructions on this website then this will be the case.

Some changes will be related to the new version and no action is necessary. Others will be your customisations which you are likely to want to replicate in the new version.
Files most likely to contain customisatians include:
Files most likely to contain customisatians include:
- server.xml
- tomcat-users.xml
- context.xml
If the ONLY changes to a file are your changes you can simply copy it over.
cp /tomcat/${OLDVER}/conf/server.xml /tomcat/${TOMVER}/conf/server.xml
cp /tomcat/${OLDVER}/conf/tomcat-users.xml /tomcat/${TOMVER}/conf/tomcat-users.xml
cp /tomcat/${OLDVER}/${WAMDIR}/context.xml /tomcat/${TOMVER}/${WAMDIR}/context.xml
NOTE: If there are other changes then you should redo your changes in the new file.
Redo any Tomcat Security changes.
