Can you point to real Annex work connected with Legacy Modernisation & Platform Transformation?

Legacy Modernisation & Platform Transformation · 2026-09-11

A useful published example is **A personalised customer portal**. 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. Throughout our engagement Annex worked closely with ActewAGL developers to provide the team with tools and systems to deliver new features quicker than ever before, optimising the code and ensuring the whole platform has automated tests. It is relevant because it shows Annex applying legacy modernisation & platform transformation to a real delivery problem rather than describing the capability only in theory. The exact scope of a future engagement would still depend on that client's users, constraints and existing environment.
