Why perform Oracle Data Centre Rationalisations... Reduce Costs associated with multiple locations Power, management, cooling, lease... Increase Resilience to Natural or Man Made factors Flooding, power availability, political stability Improve Regulation, Data Protection or Data Security, Less surface areas exposed to attack Business drivers are different for each business... 2 2012 IBM Corporation
A Data Centre Migration is a huge undertaking Your IT systems need to be up-and-running 24 x 7 Unplanned and extended outages are out of the question You must reduce risk to the absolute minimum however: Lift & Shift, Upgraded Infrastructure, Consolidated Infrastructure, Platform Migration? Oracle Upgrade, As-Is or Transformational Migration? Oracle Applications tend to be complex and often mission or business critical 3 2012 IBM Corporation
IBM Data e-business Centre Migration Solutions Centre Technical of Excellence Sales (ets) How do you run an Oracle data centre migration, minimise risk and continue to run your business? 4 2012 IBM Corporation
What is the Data Centre Migration Centre of Excellence? An IBM global community of experts With a wealth of migration knowledge and experience Applying tried-and-tested methodologies that reduce risk For a range of clients across all industries Includes the Oracle Migration Factory Automated and repeatable migrations and upgrades 5 2012 IBM Corporation
Get the Migration to Pay for Itself by Reducing its TCO Any Migration will cost Money Don t forget about all the testing resources you ll need Don t assume that internal resources are always free Power, Environment, Management & Space: All add to the Total Cost of Ownership Are not individually on a downward cost model Infrastructure can be used to pay for the migration If you have too much or its old, its costing you more money than it should Get it sized right, less OS Support Costs, less Management Costs Reduce Oracle licenses required to run the same workload Moving platforms during a migration does not add significant risk, can be used to take advantage of technology improvements Cloud, Business Process Outsourcing? 6 2012 IBM Corporation
Oracle Upgrade Types during Rationalisation Transform Functional Transformational/Re-implementation Upgrade Extensive business process remodelling Several new modules are being implemented Significant change management impact to your organisation Increased complexity requires more focused planning and program management Typically requires a re-implementation Functional Upgrade Leverages technical baseline Some introduction of new functionality and modules Limited process design focused on new functionality May have some change management impact De-customisation analysis Technical Technical Upgrade Migration of existing Oracle system to the most recent stable version of the application Conversion of data Rigorously tested and validated Mostly a technical effort 7 2012 IBM Corporation

A structured Data Centre Migration Method reduces risk The IBM method consists of a full-lifecycle approach of six stages Initiation, Discovery, Design, Build, Execute, Close Our proven and repeatable approach leverages lessons learned and local best practice It considers a range of issues defined in 5 towers Business, Applications, Technology, Operations and People There are over 50 specific activity groups, further broken down into hundreds of tasks Pic & Mix Approach to Activity Groups & Tasks The method is based on years of experience in planning, managing and performing data centre migrations. 10 2012 IBM Corporation
IBM s Data Centre Migration Method 11 2012 IBM Corporation
Stage A: Initiation To get it right first time, data centre migration requires significant and dedicated resources. It must be the core mission not just a side project Ensuring everyone involved has a clear understanding of the programme objectives from beginning to end is crucial The Programme Definition Document provides a single reference point 1. Guiding principles steer the decision-making framework 2. Risk Assumptions Issues Dependencies (RAID) analysis covers control and mitigation 3. Baseline discovery data defines the programme scope in terms of assets to migrate 4. Organisational breakdown structure identifies how people will be organised and their responsibilities 5. Work Breakdown Structure allocates the work to the teams 6. High-level plans and milestones control activity start and end times, combined with progress measurement. 12 2012 IBM Corporation
IBM Data e-business Centre Migration Solutions Centre Technical of Excellence Sales (ets) When faced with the design and planning challenge of a complex data centre migration project, it is vital to work from a common, shared base of information. 13 2012 IBM Corporation
Stage B: High level Discovery and Planning With any data centre migration, a single version of the truth should be the goal for all baseline data: hardware, software, application information, interfaces, middleware, shared services, support IBM s Discovery Data Model is specifically designed for the entire lifecycle of a data centre migration Once a trusted discovery baseline has been established, discovery management information can be extracted and detailed planning can commence 14 2012 IBM Corporation
Stage C: Detailed Discovery and Design Defining the migration architecture is vital A Migration Architecture is the technology, method, process and procedures chosen to migrate the applications and data Many factors shape the detailed plan either enablers or constraints Hidden constraints within the business must be fully understood and the business must be engaged early on in the design stage Early key decisions must be made around the: Migration approach Test strategy Approach to networking These decisions must be fact-based and will shape the migration strategy and architecture. 15 2012 IBM Corporation
Stage D: Build and Test Build is the process that establishes the technology foundations for the job, including: Data centre fabric buildings, halls, partitions, cages, space, power and cooling Physical equipment racking, structured network cabling, fibres, power distribution and outlets Production WAN and target data centre LAN WAN and Internet connections, LAN switches, security stacks firewalls/dmzs/appliances Migration facility temporary network links, boundary controls for test bubbles, etc Tooling and automation for the migration of images and data ISV Involvement for the migration of Oracle applications and business logic 16 2012 IBM Corporation
Stage D: Build and Test continued Testing spans the entire lifecycle of the migration: 17 2012 IBM Corporation
Stage E: Plan and Execute Migrations In the run up to a migration event (T- 8 weeks), it is critical to run testing to ensure that the infrastructure is ready Just like any major performance, rehearsals are the key to success There may be several migration events which take place out of hours. Careful resource management is vital to avoid burn out. An add to the day job approach just doesn t work There are several tools and techniques for managing migration events that ensure everyone understands the critical path and associated activities 18 2012 IBM Corporation
Stage F: Clean up and Closure Monitor post migration systems health Hand over to BAU teams Update Infrastructure Inventory (Asset Management) Decommission remaining infrastructure Perform lessons learnt 19 2012 IBM Corporation
