Introduction
The current information technology (IT) infrastructure consists of a mix of 2008 and 2008 R2 servers, with two legacy Windows 2000 servers, and four Windows Server 2012. In addition to the Windows server environment, the network consists of routers, switches, and security appliances, such as firewalls. The environment also consists of important services to ensure the security, and stability of the network.
The identity infrastructure is contained within Active Directory, which provides security, authentication, and authorization of identities (Training Solutions, 2014). The DHCP and DNS service are also provided to ensure reliable name resolution, and dynamic IP address assignment to the network devices that require dynamic IP address assignment. Finally, there are storage devices that contain a hybrid solution of storage area networks (SAN), and network attached storage (NAS). …show more content…
Windows 2000 has been out of extended support since 2010 (Short, 2009), as such this operating system puts the company at significant risk. Migrating the infrastructure to 2012 R2 will mitigate vulnerabilities introduced by older operating systems, and enable new capabilities within the infrastructure.
Migration Strategy
Based on the existing infrastructure there is an opportunity for consolidation, and optimization. There are currently ten DHCP servers, two file servers, and four print servers. These servers will be migrated as virtual machines, and the number of DHCP servers will be reduced from ten, to five. There are nine DNS servers, which will be decommissioned and the hosted zones will be added to Active Directory as AD integrated DNS zones. The five AD servers should be sufficient enough to support the name resolution requirements of the organization. Figure 1. Server Migration
