## Choose AI-assisted code migrations when...

- You want faster routine migrations.
- You prefer automated processes.
- You handle frequent updates.

## Choose Manual code migrations when...

- You have complex architectural needs.
- You require full control over migration.
- You face unique challenges.

## Our Recommendation

AI migrations are dramatically faster for routine changes. Manual migrations remain necessary for complex architectural decisions. Best approach combines both.
