To avoid port conflicts, make sure the old Apache Tomcat instance as well as
the old Talend Administration Center are
stopped.
Install the new Apache Tomcat server as well as the Talend Administration Center.war file.
If you have previously set a CATALINA_HOME system variable, make sure to
update it.
Note that, if you want to rename the Talend Administration Center
application during migration, the best practice is to rename the backup of the old
application in order to always keep the same URL for the application that is
currently installed. For example, rename the backup application
org.talend.administrator.old and keep the
org.talend.administrator default name for the application
that is currently installed.
Restart Apache Tomcat.
