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

Legacy Modernisation & Platform Transformation · 2026-09-08

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.

Related follow-upWhy are technical debt, migration, architecture, content and UX part of the Legacy Modernisation & Platform Transformation conversation?

The connection matters because technical debt, migration, architecture, content and UX influence the same end-to-end experience.

Related follow-upWhat happens if a client already has a legacy CMS, portal or fragmented application estate?

Yes, that can be possible; Annex's published work includes delivery inside existing technical and organisational environments rather than only greenfield builds. Throughout our engagement Annex worked closely with ActewAGL developers to provide the team with tools and systems to deliver new features…
