Rising Integration needs within enterprises and between partners necessitate migrating to new technology platforms and remove the security vulnerabilities and supportability constraints. Migration to a cost-effective and robust platform requires intense planning to avoid operational disruptions.
Digital transformation is becoming a necessity within an organization to keep pace with the emerging customer demands. One of the prime reasons holding the digital transformation path within any enterprise is their dependency on the Legacy platforms. Either the legacy applications managing the core enterprise operations or the antique integration platforms acting as middleware for B2B and A2A needs, they are still the backbone of many organizations. These 2 scenarios are very critical that holds back the organization by having incompatibility issues with modern software systems. OEM support for most of the legacy platforms have been stopped and with no upgrades or patches, Legacy platforms are the most vulnerable to security threats. Having dedicated resources to manage the old infrastructure increases the cost and leads to support overhead and multiple failure points.
Devil is in the details. Capturing all the business and technical details consume energy and migration is half done when details to the nth level are laid out.
This process also presents a unique chance to optimize existing integration process and deprecate outdated logic and interfaces. Potential security vulnerabilities are assessed and laid out.
With many numbers of interfaces and endpoints to be migrated, it always makes sense to group them logically and migrate in a phased manner.
Project timelines and external dependencies also play a major role in prioritizing the interfaces.
As the number of interfaces implementing an integration pattern increases, it makes real sense to spend more time designing those patterns and make them available for reuse to reduce the implementation timeline.
Connectivity to all integration endpoints from the new platform also plays a key role in the implementation.
Considering the fact that the old platform is supporting millions/billions of businesses, one of the critical objectives of the migration process is to have the least impact on the ongoing business. A robust testing process is required to not jeopardize the production interfaces.
Testing with business partners and customers are done based on volume, criticality and their availability.
Once we have all the interfaces tested and deployed in new integration platform, Production cut-over must be done based on the following factors
The phased delivery model combined with a high emphasis on leveraging automation frameworks and productivity tools ensure a smooth transition, consuming less time and money for the migration.
