License violation risk and outdated stack pose significant risks. - -### Q: Can we just upgrade Play without migrating to Pekko? -**A**: Yes, but you'd need to pay for Akka commercial license for production use with newer Akka versions. - -### Q: How risky is this migration? -**A**: Medium risk. Pekko is binary compatible with Akka 2.6, but Scala upgrade adds complexity. Mitigated by thorough testing. - -### Q: Will there be downtime? -**A**: Minimal. Blue-green deployment strategy allows zero-downtime migration. - -### Q: What if something goes wrong? -**A**: Comprehensive rollback plan included. Can revert to previous version quickly. - -### Q: Do we need to rewrite our actors? -**A**: No. Actors work identically.
