Risk Categorization
The total score determines the migration effort level:
Low Effort (0-25 points)
- Simple migration with minimal complexity
- Few custom configurations
- Standard security requirements
- Basic monitoring needs
- Single-region deployment
- Limited number of applications
- Standard retention periods
- Basic disaster recovery needs
Medium Effort (26-50 points)
- Moderate complexity
- Some custom configurations
- Enhanced security requirements
- Multiple monitoring tools
- Multi-region considerations
- Moderate number of applications
- Extended retention periods
- Standard disaster recovery
High Effort (51-75 points)
- Complex migration
- Multiple custom configurations
- Strict security requirements
- Complex monitoring setup
- Multi-region deployment
- Large number of applications
- Custom retention periods
- Advanced disaster recovery
Very High Effort (76+ points)
- Extremely complex migration
- Extensive custom configurations
- Enterprise-grade security
- Complex monitoring ecosystem
- Global deployment
- Large application ecosystem
- Complex retention policies
- Enterprise disaster recovery
Best Practices
- Complete all sections accurately
- Consider both current state and target requirements
- Review recommendations carefully
- Plan for the highest complexity areas first
- Consider phased migration for complex scenarios
- Validate assumptions with Confluent Cloud documentation
