Questions

Frequently asked questions.

What is the difference between Magento customization and core overrides?

Customization uses supported extension mechanisms. Core overrides modify Magento core files directly.

Can core overrides be removed later?

Yes, but refactoring overrides into proper custom modules requires planning and testing.

How can teams identify existing core overrides?

Code audits and version control reviews typically reveal direct core file changes.

Are core overrides ever recommended?

In most cases, no. They should only be used temporarily when no supported alternative exists.

Do core overrides affect performance?

They can. Overrides often bypass optimized flows and complicate caching and indexing behavior.
