Scripted migrations: fast, repeatable and verifiable
Manual migrations are slow and risky. We script everything, from infrastructure and schema conversion to data sync, parity checks and DNS cutover, so we can rehearse it until the real cutover holds no surprises.
▸ provision target infra ............ done 4m12s
▸ schema convert + apply ............ done 38s
▸ initial load (412 GB) ............. done 1h07m
▸ CDC replication lag ............... 0.8s
▸ row-count + checksum parity ....... 100%
▸ smoke tests (148) ................. pass
▸ projected cutover window .......... 6 min
Everything you need, nothing you don't
Everything scripted
Infrastructure, schema, data load, CDC sync, validation and cutover all run from version-controlled scripts.
Unlimited rehearsals
We run the full migration as many times as needed on production-sized data to fix issues and time the window.
Automated parity checks
Row counts, checksums and sampled record comparisons confirm the target matches the source.
Schema & code conversion
Data types, stored procedures and queries converted for heterogeneous moves, with automated tests.
Short cutover windows
Continuous replication means the final switch usually takes minutes.
Full audit trail
Every run is logged and timed, which is useful for auditors and post-migration reviews.
How an engagement runs
Assess
Source inventory, data volumes, change rates and compatibility gaps.
Script
Infra, conversion, load and sync automation, plus validation suites.
Rehearse
Full dry runs with parity reports and timing until results are consistent.
Cut over
Freeze writes, drain replication, switch traffic and verify.
Decommission
Source kept read-only for a safety period, then retired cleanly.
Homogeneous and heterogeneous, both scripted
Homogeneous
Same engine, new home: MySQL to Cloud SQL or RDS, PostgreSQL to AlloyDB or Aurora, or self-managed to managed services. Replication-based cutover keeps downtime to minutes.
MySQL → AuroraPostgres → AlloyDBVMs → GKE / EKSHeterogeneous
Different engine or cloud: AWS to GCP and back, Oracle or SQL Server to PostgreSQL, on-premise to cloud. We convert schemas and code and check data parity automatically.

Is migration to AWS free?
For eligible workloads moving from on-premise or another cloud provider to AWS, yes. We use AWS migration programmes and credits as a registered AWS Partner, and confirm eligibility in a free assessment.
What's the difference between homogeneous and heterogeneous migrations?
Homogeneous migrations keep the same engine, such as MySQL to Amazon Aurora MySQL. Heterogeneous migrations change the engine or platform, such as Oracle to PostgreSQL or AWS to Google Cloud, and need schema and code conversion.
How fast can a scripted migration be?
Once the scripts exist, the full process runs in hours rather than weeks. The final cutover usually takes minutes because data is replicated continuously beforehand.
Do we keep the scripts?
Yes. They're delivered in your repository, documented and reusable for future environments or regions.
Which tools do you use?
Native services such as AWS DMS and Google Database Migration Service where they fit, plus our own scripts for orchestration, validation and cutover.
