I'm glad to hear that Steve!

to recap--
Get same version JVM installed on new tomcat
Get same version Tomcat installed (with manager and admin working) on new Tomcat
copy over jars from $CATALINA_BASE/shared/lib/*.*
copy over class files from $CATALINA_BASE/shared/classes/*.*

if you see extra jars or class files located in either
$CATALINA_HOME/common/lib or
read this
once you feel you grasp the implications of what jars should be located in the common folder
then copy jars and classes only on a as-needed basis

All of your webapps live in a self contained package called WebAppName.war  
(confirm by viewing folders located at  $CATALINA_BASE/webapps 
and all war files located at $CATALINA_BASE/webapps/*.war)
you should use the manager of the new server to open each war file and carefully note any
error messages at top of manager screen 
If the top of the manager screen displays errors 
then view the tail end of the log file located at $CATALINA_BASE/logs/HostName.YYYY-MM-DD.log
