How The4 migrated Shopivet to Kalles 5.4.1 while preserving its storefront
Customer: Shopivet
About: Shopivet is a veterinary and pet-supplies store with an extensive animal-based catalogue and Arabic storefront content.
Industry: Veterinary & pet supplies
A theme upgrade needs to preserve the details customers already rely on. Shopivet asked The4 to migrate its store from Kalles 4 to Kalles 5.4.1 while carrying over its navigation, Arabic translations and customized pages. The brief also made site speed and a straightforward route to ordering important priorities.
The Challenges
The existing theme contained more than a standard collection of sections. The migration needed to account for the store's accumulated changes:
- Carry over the mega menus and category menu from the old theme.
- Transfer the existing Arabic storefront content and check language coverage.
- Preserve custom pages, product templates, collection templates and other modifications.
- Review navigation behaviour and the customer journey without treating a newer theme version as proof of faster performance.
The Solutions
Rebuilding the navigation in Kalles 5.4.1
The4 worked on the main menu and category navigation as part of the migration. The implementation notes document changes to menu layouts and hover behaviour, along with collection filtering, pagination and styling. Customer feedback was used to identify submenu behaviour that needed further attention after the initial review.
Carrying over Arabic content and custom templates
The migration scope included the store's Arabic translation and existing custom pages. Review notes specifically covered the mobile menu, footer items, language behaviour, custom collection layouts and product templates, helping the team track the differences that mattered to the customer.
Keeping a record of custom changes
The team maintained a changelog of edited and added theme files so the customer would have a reference for a later upgrade. This documented the custom work instead of leaving the next migration dependent on memory.
The Results
The source task is marked COMPLETE, and its comments record that the customer published the upgraded theme. Subsequent notes document navigation updates and a follow-up request for speed optimization.
The supported outcome is the Kalles 5.4.1 migration and the recorded navigation work. Performance remained a follow-up topic; no measured speed increase, conversion uplift or claim that every later optimization was complete is made here.
Conclusion
Shopivet's project illustrates why a major theme upgrade needs a careful inventory of menus, languages and custom templates. The4 handled the migration work against the customer's existing setup and documented the changes for future maintenance.
