This Knowledge articles describes the steps to manually upgrade from Tomcat 7.x to 8.x or from one 7.0.xx version to a higher 7.0.xx version on Portal servers running on Linux OS.

In the below example we are upgrading from Tomcat 8.5.15 to Tomcat 8.5.23. However these same steps should be applicable when upgrading from Tomcat 7.x to any version of Tomcat 8.x or from one 7.0.xx version to a higher 7.0.xx version.All these steps are applicable to Portals running on Linux OS. 

/opt/aptare/bin/tomcat-portal stop
/opt/aptare/bin/tomcat-agent stop
cd /opt/
wget http://<aptare.comlinkfornewapachetomcatdownload>/apache-tomcat-8.5.23.tar.gz
gunzip apache-tomcat-8.5.23.tar.gz
tar -xf apache-tomcat-8.5.23.tar
rm apache-tomcat-8.5.23.tar
cd apache-tomcat-8.5.23/bin/

To download from the web, you can, for example, use 

wget http://download.nextag.com/apache/tomcat/tomcat-8/v8.5.23/bin/apache-tomcat-8.5.23.tar.gz

Note however that the non-APTARE distributions downloaded directly from the web will NOT have the required sc.properties file, so that file with appropriate contents will have to be created manually
