Who We Are
• Kishwaukee College is a community college founded in 1968, located amongst the beautiful cornfields of Malta, IL.
• Located 6 miles west of DeKalb, IL and Northern Illinois University

Why We Had To Migrate
• Servers had reached End Of Life• Tired of beta testing software• Direction of the product at Datatel• Needed Colleague to better integrate with

The New Hardware Platform

The New Hardware Platform
• Completely Virtual Environment• VMware vSphere 4.1 (Vcenter/ESXi 4.1)• 6 Host Servers
– 4 HP DL380G6 – Dual Quad Core Xeon x5550 64GB RAM
– 2 HP DL380G7 – Dual Six Core Xeon X5650 192 GB RAM
• 17 TB Usable Storage Currently• Changing out 2 of the G6 servers for 2 HP
DL380G8 servers (Dual Eight Core Xeon E5-2690 224GB RAM) during Summer 2013

The Test Migration

The Test Migration
• Data brought into new environment• Because we were an Oracle school, data was pretty
clean• Had to figure out how to identify our custom code
(not too much custom) and install• Had to setup a new (virtual) WebAdvisor server as
well as a new (virtual) DMI server• Setup authentication• Identify users to test and let them do their thing• AR.INVOICE.ITEMS
