Hello furquan,
The files should all be located in /usr/local/jakarta/apache-tomcat-5.5.28 location. Most of them should be the same no matter what version of Tomcat is installed, but the server.xml in /usr/local/jakarta/apache-tomcat-5.5.28/conf/ location would contain the domain configurations.
Additionally, there will be configuration include files in /usr/local/apache/conf/userdata/std/ location for each individual user and domain (the path will vary depending on your Apache version so I can't provide the exact path). These will be called cp_jkmount.conf for each file for each user and contain the following lines approximately:
Code:
<IfModule mod_jk.c>
JkMount /*.jsp ajp13
JkMount /servlet/* ajp13
JkMount /servlets/* ajp13
</IfModule>
You could simply install Tomcat onto the new machine and re-add JSP for each domain listed in /usr/local/jakarta/apache-tomcat-5.5.28/conf/server.xml file. If the accounts have war files, they should auto extract on Tomcat restart anyway for the domain addition, so you shouldn't have to copy anything beyond making sure each domain has JSP and servlets installed onto it. The version of Tomcat cPanel uses in the newest EasyApache is 5.5.33, which isn't that much later than the version you are using right now.
The only reason I can even see copying that data would be if you've made any configurational changes to the server.xml beyond the default settings.
