Thanks, @Khaja_Zaffer and @BS_THE_ANALYST!

@Khaja_Zaffer:The toolkit has 5 main components:

1. Pre-migration analyzer  Compatibility scoring
2. Drift monitor Real time consistency checks
3. Permission migrator: Automated ACL copying
4. Query rewriter: Hive→UC SQL converter
5. Rollback orchestrator: one-click recovery

@BS_THE_ANALYST: Excellent observation! This isn't typical; most use downtime. The 3 weeks with zero stale data worked because:

# Dual-write pattern every transaction hits both systems
write_to_hive(df) + write_to_uc(df)  # Atomic operation

• Week 1: Historical sync
• Weeks 2-3: Dual writes (keeping data fresh) + gradual user migration

The dual-write ensures data is ALWAYS current in both systems. No catch-up needed!

You're right that downtime is simpler (one snapshot, done), but for 24/7 operations, this complexity pays off.

Happy to dive deeper into any specific aspect!
