Oxygen v4-to-v6 Migration

I need my current WordPress site, built with Oxygen Builder 4.x, moved to Oxygen 6 while preserving every layout, style and interaction exactly as they are now. No plugins, content or extra assets have to be touched—this is strictly a theme migration.

Because I’m not certain whether the site has any custom snippets tucked into templates or Code Blocks, I’ll rely on you to audit the install first, flag anything that could break in 6.0, and then replicate or refactor that code so the front-end looks pixel-perfect once the upgrade is complete.

Typical steps I expect:
• spin up a staging copy of the site,
• export/import the Oxygen design set into 6.0 or rebuild directly,
• test responsiveness, dynamic data, and any conditional logic,
• push the updated theme to production with zero downtime.

Please be comfortable working inside Oxygen’s Structure panel, Re-usable Parts, global colors and CSS classes, and have a workflow for quick rollback should something go wrong. When finished, I want a clean Oxygen 6 install running the identical design, along with a short report of any code you changed or removed.
