It is unclear here if you have the HP application installed or not on
7.0.53 in you VM. If you don't, it is pointless to backup any content. The
idea of the backup is to keep a copy of the working configuration for

No, don't blindly copy contents. You can copy the WAR file in the webapps
folder. But you shouldn't just copy over the conf content. Usually, only
the server.xml is modified and you must look at the actual content and
adapt to your particular needs. The old copy being a reference provided it
is not just a vanilla copy.

If you have SSL enabled you should look into the server.xml for the files
you need to keep. You can relocate them provided you update the location in
the server.xml.

You must understand what you are doing. You cannot just blindly copy
everything and expect it to work. Usually, the Tomcat configuration is in
conf/server.xml and the web application configuration is in
webapps/whatever_name/WEB-INF/web.xml. However, with HP you may also have
other files in WEB-INF to edit to configure the application properly.

WAR is the standard to distribute web applications.
