Scenario
A. Datum Corporation has a head office based in London, England, and has a mix of Windows Server 2008 and Windows Server 2003 servers. The AD DS environment is based around Windows Server 2008 R2 domain controllers.
The regional hub sites (Toronto and Sydney) have a predominantly Windows Server 2008 based infrastructure, while the smaller, regional branches and distribution centers have Windows Server 2008 servers that support line-of-business (LOB) applications.
The management team at A. Datum has stipulated that the new IT infrastructure must be more efficient in terms of hardware utilization and power consumption. This suggests that consolidating server roles and virtualizing workloads is an important part of the server upgrade and migration plan.
You have been involved with early discussions surrounding the likely acquisition of two companies by A. Datum. This has not been formally announced, but is likely to occur in the coming months. You
understand that one of these organizations has no Windows Server infrastructure in place, and you may be required to develop a strategy for how best to deploy Windows Server in that environment. The second potential acquisition has a Windows Server 2008 forest.
However, before the server deployment can begin, you must plan a server upgrade and migration strategy. This plan involves determining which server roles will be migrated, which can be consolidated onto a single server, and whether a given workload is suitable for virtualization. Initially, you plan to perform this analysis on the servers located in London and its perimeter network only. You plan to analyze Toronto and Sydney later.
During this process, you must remain focused on optimizing server resources and capacity. In addition to these mainly technical considerations, you must also consider the implications on server licensing.

Brad Sutton 7th September Requirements Overview
To design a server upgrade and migration strategy to support the following objectives: • The new IT infrastructure must be more efficient in terms of hardware utilization and power
consumption.
• Consolidating server roles and virtualizing workloads is an important part of the server upgrade and migration plan.
• Develop a strategy on deploying Windows Server 2012 in a scenario of potential acquisition with another company that has a Windows Server 2008 forest.
• Determining which server roles will be migrated.
• Determining which can be consolidated onto a single server, and whether a given workload is suitable for virtualization.
• Initially, you plan to perform this analysis on the servers located in London and its perimeter network only. You plan to analyze Toronto and Sydney later.
• Consider the implications on server licensing.
Additional Information
• A. Datum Corporation has a head office based in London, England, and has a mix of Windows Server 2008 and Windows Server 2003 servers.
• The AD DS environment is based around Windows Server 2008 R2 domain controllers.

Network Access Services Strategy Proposals
1. You plan to run the MAP Toolkit to help you decide on server consolidation. What result do you expect to get from this tool?
2. Besides using the MAP Toolkit, what considerations would help you determine which machines you would move to the virtual environment?
3. What is your decision regarding virtualization of domain controllers?
4. What is your decision regarding virtualization of infrastructure servers LON-IF1 and LON-IF2? 5. Do the virtualized machines require high availability?
6. Should any server roles be allocated more resources?
7. What are the best virtualization candidates on internal network, considering current physical server utilization, as well as high availability requirements?
8. What are the licensing considerations of your plan?
9. What are the best virtualization candidates on the perimeter network, considering current physical server utilization, as well as high availability requirements?
10. What are the licensing considerations of your plan for perimeter network servers? 11. How would you manage licensing and activation?
12. Sketch the relevant network areas of your plan. The main tasks for this exercise are as follows: 1. Read the supporting documentation
2. Update the proposal document with your planned course of action 3. Examine the suggested proposals in the Lab Answer Key
4. Discuss your proposed solution with the class, as guided by your instructor.
