Step 1:Don't just evaluate - VALIDATE the best approach
First, you need to take the time to map your current IT landscape. This will give you a clearer picture of the best approach for your platform migration. You should identify which mission-critical workloads, applications and databases are essential to your business. Most importantly, assess and validate which target platforms are best suited to support their needs.This is particularly important for organisations with offices spread across multiple locations, and those that have complex,multi-tier databases and applications.
Step 2: Develop your IT roadmap with a compelling business case
A strong business case is a pre-requisite for gaining business buy-in for your platform transformation.To frame important migration decisions, your case must cover business drivers and key business processes. It must also show change impacts and total cost of ownership analysis. You should also state the potential business risks and costs associated with not taking any immediate action; leaving it too late can be as disastrous as not migrating at all.
Your roadmap should provide a high-level timeline for the migration process, which is usually in phased stages for large migrations. It should also identify quick wins to gain an early return on investment and makes your business case even more convincing.
Step 3:Mitigate business risk through careful design and planning
Once you've developed your roadmap, the design and planning stages should involve setting specific priorities and schedules for migrating each application. This way, you can effectively reduce any risks that may arise during the transition and minimize any potential business disruptions.
In order to shift seamlessly to your new platform and transition without a glitch, your priorities should include:
- Identifying older priority applications that need to be upgraded, migrated, or sometimes replaced.
- Evaluating customisations and code extensions that are need to be migrated or replaced.
- Optimising your existing IT infrastructure to make the most of what you already have. This will help deliver higher performance while reducing costs.
Lower risks, higher returns
Platform migration does not have to be the high-risk, high-cost challenge that many CIOs fear.By far, the greatest risk comes from delaying such migrations. Inflexible, legacy systems are costly to maintain and are too slow to respond to today's business demands. For mission-critical workloads that is a bad option.
A carefully planned migration process can result in a seamless transition for your business. By aligning technology to support your company's business priorities, the rewards will be quickly realised. Your new technology environment will deliver higher levels of performance and efficiency, greatly improved availability and increased innovation -- all at a lower cost. In turn, you will be viewed as a trusted advisor who not only safeguards critical IT systems, but also drives positive business outcomes.
