在新的WSO2 - ESB安装上启用数据服务

I am trying to migrate an installation of WSO2 - ESB from an old 2003 server to a new 2012 server. The old server had version 2.0.2 while the new server has version 4.8.1. The application is running and I can log in and browse the system. The problem I have is that it appears to be missing components. For example, on the old server there are a list of services including: Proxy, Data, POJO, Spring, Jar ect..on the new server I only have Proxy service. The main service I only need is the Data service but I have no idea how to get that. I am completely new to Java and this application however my boss wants this up and running as the Data service we had on the old server is designed to pull a data feed from a remote SQL server and push it to another server we have. Please help, I have absolutely no idea how to proceed.I am trying to migrate an installation of WSO2
