Supporting Sirromet's migration from Kalles 4 to Kalles 5.4

Customer: Sirromet Winery

About: Sirromet is a Queensland winery with an online wine store and a wider website covering dining, winery experiences, events and accommodation.

Industry: Wine and hospitality

A theme migration for a hospitality business needs to account for more than a shop homepage. Sirromet's project brought together wine collections, navigation and pages supporting visits to the estate. The4 supported a move from Kalles 4 to Kalles 5.4, with the brief calling for existing content and functionality to carry forward.

The Challenges

The site used a range of page and collection templates. The customer stressed that templates temporarily hidden from navigation could still be part of the operational website and needed to be included in the migration.

The navigation also required custom work. Early implementation notes identified three mega menus that needed customization, followed by a new header-menu implementation and styling work.

The Solutions

Rebuilding the theme-owned storefront elements

The project record documents implementation work on the homepage, a custom header and the default collection page. The team also recorded work on the Cellar Door and booking-related pages within the migration.

Reviewing pages across several rounds

The handoff included several rounds of QA, with separate checks recorded for collection templates and key pages. The customer then reviewed the migrated theme and flagged page templates that had not yet been recreated, asking the team to cross-check the old and new versions.

Keeping the final launch account accurate

The final customer update confirmed that the new theme had been published. That update also reported small remaining oversights in link behaviour and text styling, which the customer said they had corrected themselves. The launch therefore reflects both The4's migration support and the customer's final review and corrections.

The Results

The source record confirms a published Kalles 5.4 theme following the implementation and review process. It does not establish that every requested template or final detail was completed by The4 alone. No measured speed, revenue or conversion improvement was supplied, so none is claimed.

This project is a theme migration. It is separate from Sirromet's custom EComposer accordion project.

Conclusion

Sirromet's migration highlights the importance of reviewing the full template inventory when moving between major theme versions, including pages that are temporarily hidden. It also shows why the final handoff should distinguish implementation work, customer feedback and the corrections made before publication.
