Which system carries the shop, how is it structured, and what happens when you switch? This category collects articles on the technical foundation: Shopware CE as an open base, extensions and their maintenance effort, front-end approaches, multi-client capability and how much custom development is reasonable. A second focus is migrations — from legacy systems or from home-grown solutions: data transfer, URL structure and redirects, testing procedures, switching over during ongoing operation. We describe architectural decisions in a way that non-developers can judge the consequences too, for example regarding running costs, upgradability and dependencies. Where statements depend on the specific starting position, we say so. We also add notes on evaluating extensions: which questions to ask a vendor before purchase so that upgradability is preserved.
