Getting ready for WordPress 7.0 — three things to check now: PHP requirements, FSE migration, and editor extensions

Short summary

A practical pre-flight checklist for WordPress 7.0 covering three risk areas: PHP minimum version increases breaking older plugins, Classic-to-Block Theme migration friction, and editor extension compatibility with Gutenberg's collaborative editing phase. Each section includes WP-CLI commands to audit current state and concrete guidance on sequencing upgrades to isolate failure causes.

  • •Check PHP version and plugin update status via WP-CLI to flag PHP 8.x compatibility risks
  • •Identify Classic vs Block Theme sites and estimate migration cost separately from core upgrade
  • •Audit editor extensions for compatibility with Gutenberg Phase 3 collaborative editing changes

Generated with AI, which can make mistakes.
