Hello, We will upgrade your existing Ionic 3 and Angular 4 application to the latest Ionic 7 framework with Angular 15 using a structured and reliable migration approach. The work will begin with a detailed review of the current codebase, dependencies, Cordova plugins, and Android configuration to identify deprecated features and required replacements. Based on this assessment, a fresh Ionic 7 project will be created with Angular 15 and routing fully configured following current best practices. To validate the setup, we will implement at least one sample page and service that demonstrates navigation, API integration, and successful interaction with the native Android layer using Capacitor. This will confirm that the upgraded architecture works smoothly and is ready for further feature migration. Android-specific configuration will include setting up signing configurations, build variants, and generating Play Store–ready AAB or APK files. We will ensure the project builds without errors using ionic build android. The final deliverables will include the Android build artifact (.aab or .apk), the complete source code in a Git repository, and a concise README detailing environment prerequisites, setup instructions, and build steps. The overall upgrade is expected to take approximately 12-15 working days, resulting in a stable, maintainable, and future-ready application foundation.
