Comparison
Upgrade Radar vs Manual checking
67% of the Manual checking cells below carry a cited source — a dossier reference, a content snapshot and a capture date. The rest say "not verified": never invented, never blank. Full sourcing: the comparisons index.
| Feature | Upgrade Radar | Manual checking |
|---|---|---|
| Compatibility check method | A 37-rule composer-semantics engine evaluates every plugin's declared shopware/core constraint against your target version, with the constraint quoted | Read each plugin's composer.json by hand, then run `composer update --dry-run` to simulate resolution without changing anything (ref: manual-check-method-001, snap: 372cb1e1, 2026-08-17) |
| Vendor-recommended pre-upgrade step it follows | None needed — the check itself is the automated pre-upgrade step | Shopware's own upgrade guide: "Automate pre-upgrade checks (PHP/DB versions, extensions, disk space)." (ref: manual-check-vendor-guidance-001, snap: 187697a4, 2026-08-17) |
| Undeclared-constraint handling | Reported as unknown, never assumed compatible | not verified |
Check a real shop
Run your composer.lock through the checker — it reads declared constraints the same honest way this page does.
