Product Technology Migration Services

AFourTech has a good amount of experience in catering to organizations who want to either:

Migrate existing (or legacy) technology stack to a newer version of the stack 

or

Re-engineer existing systems into a newer technology stack and support new business use cases

AFourTech help organizations migrate existing technology stack to newer technology stack in less time and with minimum cost overheads.

Organisations over time need to keep abreast with the latest technology stack in their product offering. Often times this means upgrading the version of the technology stack, libraries and tooling to a newer version. Newer versions of the technology usually make changes in the codebase, and hence the applications are not easily upgradable. Sometimes, in order to support newer business and use cases, the application may need re-engineering and re-architecting to be able to use with the new technology stack.

AFourTech helps organizations with requirements to upgrade their systems and applications with the needed technology.

Methodology

AFour follows a scientific approach to technology migration and has a sizable amount of experience in upgrading and migrating technology stacks, re-engineering, and re-architecting systems. AFour follows a unique philosophy to migrate and understands that following aspects need to be delivered and handled too:

Requirements engineering

Experts at AFourTech connect with customers and understand their pain areas and the ‘why’ for technology migration / upgradation. As described, two broad use cases make the cause for migration:

  • Upgrading technology stack version to a newer version
  • Re-engineer and re-architect applications in order to cater to new business and use cases

Once the requirement is identified, the next step includes working with the customer teams to know more about the requirements and dependencies and getting hold of artifacts in order to make the right technology choice.

Technology selection

If a legacy technology needs to be updated to a newer version, there are little choices available. Sometimes, customers may not like using a new technology stack all together and may prefer using the newer versions of the existing stack. Based on constraints such as these, technology choices are then evaluated and discussed thoroughly with the customer. AFourTech also builds proof-of-concept applications and demonstrate to the customer to evaluate out some possibilities, if the need arises.

Customers want to re-engineer and re-architect their systems to support use cases. AFour helps in choosing and evaluating technologies to build great products and save time in re-engineering and re-architecting. One of the good examples which require re-engineering and/or re-architecting applications is when organizations want their existing on-premise applications to be deployed to the cloud. Helps choose a cloud provider and its services with the minimum total cost of ownership.

Re-architecting and re-engineering

Re-architecting and re-engineering a product or a service is easier said than done and often means new development from scratch. However, it is necessary to look into the existing technical debt of the product or the service and the ‘why’s of re-development. Having said that, the re-engineering exercise must keep adhering to all existing use cases, changes in some use cases, as well as new use cases and additions too. Also, the re-development exercise must factor in dynamics like the changing demands in user needs, cloud adoption and emphasize on great user experience. With these and more, AFourTech is committed to helping migrate technology to satisfaction.

AFourTech applies industry standards and best practices followed across to build great applications and reduce overall maintenance and technical debts.

Documentation

A technology migration is a new system adhering to new use cases. As such, AFour helps prepare the documentation of the newer system and helps organizations to a smooth transition. Often times, customers having legacy technology stack do not have people with the expertise and enough documentation to get going. AFour helps them to make the migration and updates their documentation.

Costing

AFour helps save costs in the long run by migrating to the cloud, using open source tools and technologies and by re-architecting and re-engineering the product so as to have minimum technical debts and ease of modifications and enhancements. With a great documentation, AFour reduces the knowledge transfer time needed to the customer team and helps maintain systems easier and better.
