Upgrading @effect/* v0.x packages to Effect v4 involves API renaming, class restructuring, and module organization changes. You must modify code to accommodate these API adjustments and update all necessary imports to work seamlessly with the new v4 architecture.

Yes, you can automatically adjust TypeScript import statements to match the new Effect v4 module layout. This import path update is a core feature of the migration process, transitioning from older Effect v3 structures to the new v4 architecture.

Migrating to Effect v4 preserves TypeScript type safety by applying minimal mechanical code changes. The process focuses on updating imports and adjusting changed APIs across Effect, platform, schema, and HTTP modules without breaking type constraints.

The best way to handle API renaming during an Effect v4 upgrade is to apply minimal mechanical changes based on the official migration guide. You modify code to accommodate changes in Effect's API, classes, and module organization while preserving type safety.

@effect/platform imports break after upgrading to Effect v4 because the new version introduces a different module layout and API restructuring. You must update all necessary import paths and API calls to work seamlessly with the new v4 architecture.
