The Isle of Man Government (IoMG) went from having a highly diverse IT infrastructure in 2002 to standardising on Microsoft's software platform, and recently told Computer Weekly it will soon replace its Oracle Financials ERP system with Microsoft Axapta.

IoMG's main objectives were to reduce total cost of ownership (TCO) and better manage IT. The infrastructure originally comprised UnixWare, Novell NetWare Sun Solaris, and Windows.
Allan Paterson, director of information systems at IoMG, said, "When I started in 2002, the IT infrastructure was fragmented. We had multiple databases and versions of Oracle's desktop client, and money was going on non-IT projects. The servers were four or five years old and failing."
In 2003 the government conducted a full review of its IT assets and in 2004 embarked on a project to migrate its legacy applications to Unisys ES7000 and Clearpath servers, and adopt Windows Server 2003.
It will continue to migrate applications though 2005 and 2006 as they come to the end of their lives. One of the first migrations involved moving a flagship hospital's Oracle Financials system from Unix to a Windows Server 2003 Datacenter Edition platform.
In May, the government finished upgrading its 4,400 users' Windows XP desktops to the latest version of Office, linked by Windows Server 2003 Datacenter, SMS, Sharepoint Portal Server and Active Directory.
IoMG's IT overhaul follows three stages: it consolidated 14 Novell file and print servers onto one Microsoft box. It will soon implement a £5m Cisco-based converged voice and data IP network to support 5,000 government staff.
At the same time, it aims to move 300 servers into a second datacentre, consolidating them physically and logically on to Windows Server 2003 Datacenter, while moving applications over from older platforms.
