What role do prototypes, testing or technical proof play in Legacy Modernisation & Platform Transformation?

Legacy Modernisation & Platform Transformation · 2026-09-11

Annex's published work does not point to a single mandatory toolset for legacy modernisation & platform transformation. As a part of this transformation ActewAGL identified that their Self Service Portal was in need of upgrading and improving, since existing service was running on an outdated version of Sitecore and JavaScript causing the platform to run very slowly. Using Drupal 8 and its multilingual capability, the team created a website that can automatically translate English content into over 64 languages using google translate, and also allow manual human translation to be published when they were made available. Prototypes, technical proofs, testing and platform choices are used when they help answer a real project question; the technology is selected around the client landscape and intended service rather than the other way around.
