# Scenario: Before/After Migration Comparison

## Description

Compare a pre-cutover host snapshot against a post-cutover snapshot and determine whether the migrated system is ready for production traffic.

## Commands

```bash
cd migration-validation-framework
python3 cli.py compare examples/before.json examples/after.json --output /tmp/migration-diff.json
```

## Expected Result

- The command writes a JSON diff.
- The result is `FAIL` because `sshd` is failed after migration.
- The risk assessment highlights the `/var` disk usage increase.
- The remediation path is to restore SSH and reduce or expand `/var` before approving cutover.
