Zero-downtime Redis to ElastiCache migration (martech SaaS, NDA)
- Replication-based sync kept both caches current
- Circuit breaker in the application path to fail safe
- Traffic cut over in stages, verified at each step
0 minutes of user-facing downtime

Database Migration
Databases are the part of a migration that cannot be redone casually. The approach is always the same: replicate, verify, cut over in stages, and keep the source intact until you are certain.
No sales layer, no juniors. You meet the engineer before anything begins.
// What is included
What you get
- Replication set up so source and destination stay current during the move
- Row counts and checksums verified before any traffic switches
- A staged cutover with a way back at each step
- The source left running and intact until you confirm
// How it runs
The sequence
- 01
Replicate
Stand up the destination and keep it in sync under load.
- 02
Verify
Prove the data matches before anything is switched.
- 03
Cut over
Staged switch with rollback available at every stage.
