Our client has made a strategic decision to move the code base of its web portals away from the proprietary ATG framework and to other solutions. After careful deliberation, the selected target architecture was one using the open-source solution based on Spring and Hibernate/JPA.
The migration was planed in two phases. While the focus of the Phase 1 was on the data layer and on upgrading key technology components that were reaching end-of-life, the focus of the Phase 2 was on removing the rest of the ATG framework including the migration of the front-end code base.
With the effort encompassing two years of very intensive work, this transition brought many challenges. Not only those originating from the sheer size of the effort and time constraints imposed by discontinuation of support for the technology components, but also those related to synchronizing all project activities with the regular maintenance and other projects going in parallel.
With its knowledge of the system and broad experience gained during the last 10 years, Vicert was uniquely positioned to respond to those challenges.
