# Migration Guide

This guide provides comprehensive instructions for migrating from other enterprise search systems to Fess. Fess offers robust compatibility layers, import tools, and APIs to facilitate smooth transitions from various search platforms.

 Plugins should avoid these classes and be updated to use only Maven3 dependencies (and require Maven3): see

If you have an old FastAPI app with Pydantic v1, here I'll show you how to migrate it to Pydantic v2, and the **features in FastAPI 0.119.0** to help you with a gradual migration.

## Official Guide { #official-guide }

Pydantic has an official [Migration Guide](https://docs.pydantic.dev/latest/migration/) from v1 to v2.

It also includes what has changed, how validations are now more correct and strict, possible caveats, etc.

⚠️ Do not install this package. ⚠️

This package, `fastapi-slim`, does nothing other than depend on `fastapi`.

All the functionality has been integrated into `fastapi`.

The only reason this package exists is as a migration path for old projects that used to depend on `fastapi-slim`, so that they can get the latest version of `fastapi`.

You **should not** install this package.

Install instead:

```bash
pip install fastapi
```
