What problem does it solve? Upgrading an Ionic Framework app across major versions involves dozens of breaking changes—removed components, renamed CSS variables, changed event signatures, and new browser support requirements—that are easy to miss and tedious to apply manually. ## Core Features & Use Cases - Sequential Multi-Version Upgrades: Applies upgrade guides step by step for jumps like 5 to 8, building and verifying after each intermediate version. - Framework-Specific Migration Steps: Covers Angular, React, Vue, and Core/Standalone projects with the correct package installs and API changes for each. - Detailed Breaking Change References: Documents component removals (ion-slides, ion-virtual-scroll), CSS variable renames, form control migrations, and Jest configuration updates per version. - Use Case: You have an Ionic 6 React app that must move to Ionic 8. The skill detects the current version, applies the v6-to-v7 then v7-to-v8 guides, runs builds after each step, and fixes errors such as legacy form control syntax. ## Quick Start Upgrade my Ionic React app from version 6 to version 8 and fix any build errors along the way.
