boilerplate-upgrade

To upgrade AEM EDS boilerplate without breaking changes, you need a three-way diff analysis comparing your project customizations against the upstream baseline and the latest release. This identifies safe replacements versus files requiring conflict resolution, ensuring custom edits to core assets like scripts.js and styles.css do not cause runtime regressions.

The best way to resolve merge conflicts in EDS core files is to classify an upgrade strategy per file by computing the upstream delta versus your project delta. This determines which core files are safe to replace and which require manual merges or conflict resolution, preventing runtime regressions.

A three-way diff helps update customized EDS boilerplate by analyzing your current project customizations against both the original upstream baseline and the latest release. It produces a conflict-aware summary that isolates safe file replacements from drifted files requiring manual merge resolution.

Yes, you can generate a rollback plan for AEM boilerplate upgrades before applying changes. An automated upgrade plan includes ordered merge sequencing, before and after diffs, explicit rollback steps, and a post-upgrade validation checklist to ensure both functional and performance safety.

Upgrading aem.css and styles.css causes runtime regressions because custom edits to these core assets create hard-to-resolve merge conflicts when fetching the latest upstream versions. Drifted modifications across versions require a classified upgrade strategy to safely merge without losing project customizations.

Yes, you need to provide explicit upstream URLs for the boilerplate-upgrade process to fetch external content. The tool fetches the latest upstream versions only under user-provided or explicitly linked URLs to compute the delta against your current project baseline securely.
