  To upgrade your ABP microservice solution from version 4.2.2 to 9.0, follow these steps:

  1. Review Migration Guides

     • Carefully read the official ABP migration guides for each major version between 4.x and 9.0. Start with the ABP 9.0 Migration Guide and work backwards for each major version (5.x, 6.x, 7.x, 8.x). Apply all required breaking changes and manual steps for each version in sequence.

  2. Update .NET and ABP Packages

     • Upgrade your solution’s .NET version to .NET 9.0, as ABP 9.0 requires it.
     • Update all ABP NuGet and NPM packages in your solution to the latest 9.0 versions.
     • If you use the ABP CLI, run:

       abp update
       

     • Manually update any other dependencies (e.g., Microsoft, third-party packages) to versions compatible with .NET 9.

  3. Update Microservice Template Structure

     • Compare your existing solution structure with a fresh ABP 9.0 microservice template (created via ABP Studio or CLI).
     • Migrate your custom microservices and code into the new structure, updating namespaces, dependencies, and configuration files as needed.

  4. Apply Breaking Changes

     • For each ABP version upgrade, apply the breaking changes listed in the migration guides. This may include:
       • Module and dependency registration changes
       • Configuration file updates
       • Code refactoring for deprecated APIs
       • Changes in authentication, authorization, and OpenIddict configuration

  5. Update Configuration Files

     • Update appsettings.json, DbMigrator settings, and other configuration files to match the new template and ABP 9.0 requirements.

  6. Database Migrations

     • Update your Entity Framework Core migrations to be compatible with the new ABP version.
     • Run the DbMigrator project to apply any new or updated migrations.

  7. Test and Validate

     • Thoroughly test all microservices, APIs, and UI applications.
     • Validate authentication, authorization, and inter-service communication.

  8. Leverage New Features

     • Optionally, refactor your code to use new ABP 9.0 features and improvements.

  Tip:
  Upgrade in small increments (one major version at a time), commit and test after each step, and use a source control system to track changes.

  hi

  This gap is too wide. It's not easy to upgrade fast.

  Check the new microservices solution at https://abp.io/docs/latest/solution-templates/microservice.

  You can create a latest microservices solution. Then migrate your old service into the new solution.

  For your old services, the migration is straightforward. Please refer https://abp.io/docs/latest/release-info/migration-guides

  Thanks.
