Complete Migration in 4 Phases

1Assessment & Planning (3-5 days)
  • Automated Sybase ASE schema analysis and profiling
  • Identify Sybase-specific features (tempdb usage, locking, cursors)
  • Analyze stored procedures, triggers, and user-defined functions
  • Generate migration roadmap with risk assessment
2Schema & Code Conversion (1 week)
  • Automated schema conversion with data type mapping
  • Convert Sybase T-SQL to SQL Server T-SQL (90% automated)
  • Translate stored procedures, triggers, and functions
  • Handle Sybase-specific syntax (@@rowcount, @@error, raiserror)
3Data Migration & Validation (1-2 weeks)
  • Initial bulk data transfer with parallel processing
  • Continuous replication for zero-downtime migration
  • Automated data validation and reconciliation
  • Performance testing and query optimization
4Cutover & Go-Live (2-3 days)
  • Final data synchronization with minimal downtime window
  • Application connection string updates
  • Post-migration validation and monitoring
  • Rollback plan ready if needed

People Also Ask

How long does Sybase to SQL Server migration take?

With AI-powered automation, Sybase ASE to SQL Server migration typically takes 3-4 weeks for most databases. Traditional manual migration can take 6-12 months. The timeline depends on database size, complexity of stored procedures, and the number of Sybase-specific features used. Our AI agents automate 90% of the T-SQL conversion, dramatically reducing migration time.

Can I migrate from Sybase to SQL Server without downtime?

Yes, zero-downtime migration is possible using continuous replication. We set up real-time data synchronization between Sybase ASE and SQL Server, allowing your applications to continue running on Sybase while data is being migrated. Once validation is complete, we perform a quick cutover with minimal downtime (typically under 5 minutes). This approach ensures business continuity throughout the migration.

What are the main differences between Sybase and SQL Server T-SQL?

Key differences include: error handling (Sybase uses @@error and raiserror, SQL Server uses TRY/CATCH and THROW), tempdb usage patterns, cursor syntax, identity column behavior, and some built-in functions. Our AI agents automatically detect and convert these differences with 90% accuracy, handling complex patterns like nested transactions, dynamic SQL, and Sybase-specific system procedures.

How much does Sybase to SQL Server migration cost?

AI-powered migration costs 68% less than traditional methods. For a typical 500GB Sybase database with 200 stored procedures, expect $45,000-$80,000 vs $140,000-$250,000 for manual migration. Costs include schema conversion, T-SQL translation, data migration, testing, and validation. You also save on ongoing Sybase licensing costs by moving to SQL Server, which can be $50,000-$200,000 annually depending on your configuration.

Will my applications work after migrating from Sybase to SQL Server?

Yes, with proper migration planning. Most applications require minimal changes - typically just connection string updates. Our AI agents analyze your application code to identify Sybase-specific SQL patterns and provide recommendations for updates. We also create a compatibility layer for complex scenarios, ensuring your applications continue to function correctly. Comprehensive testing validates all functionality before cutover.
