Application Migration:
Migration of new technologies and changing business environment brings new challenges on legacy enterprise systems. VTS help our clients, migrate legacy systems to new technology like Cloud, .NET Applications etc. with an objective to boost operational performance and reduce cost.
Below are the factors that need to be analyzed, before we get into an actual migration process:
1. Understand the scope and scale of migration:
Estimation brings new challenges, unforeseen surprises and additional scope that organizations may not have considered during the initial migration assessment. There are multiple reasons include,
- Legacy systems that have gone through various changes through their lifecycle, complex to define and harder to understand their scope,
- Unavailability of design and implementation documents.
2. Minimum business impact:
Business objectives of migration include,
- Reducing the maintenance cost of legacy systems,
- Improving business processes,
- Investing in technologies that adapt to changing business needs.
Customers that have already invested in maintaining the current systems for many years they would not want to rewrite the entire system to meet business objectives. After migration, Business functionalities should be unchanged and can be re-used in target environment thereby achieving the main objective.
3. Reuse the existing and minimize the changes:
Every technologies has its own proprietary components that need to be removed while migrating to a new environment. However, most of the systems uses generic specifications to develop these applications, such as web services, standard frameworks etc. we should try to use existing stand-in processing and catch-up these open standards and frameworks in the target system.
4. Analyze the risk and define the mitigation plan:
Migrating legacy applications to new platform involves risks that need to be identified and mitigated. Risk includes, unavailability of documentation, out-of-support software and hardware, inconsistent design. These must be articulated and documented during the migration assessment phase.
