A structured rewrite of aging relational schemas with migration scripts, rollback notes, and paired review sessions for your engineers.

- PricingQuote after intake
Who this is for
Product and platform teams whose PostgreSQL, MySQL, or SQL Server schemas have outgrown the original domain model. Typical signals: tables that serve too many meanings, nullable columns that hide unfinished migrations, and feature work blocked by fear of touching the core tables.
Result you leave with
A sequenced refactor plan, migration scripts ready for review, and a written handoff covering cutover windows, rollback, and the queries that must be retested after each step.
Scope included
- Intake of schema dumps, ER sketches, and the top slow statements
- Target model workshops with your engineers and a product owner
- Forward and reverse migration scripts for the agreed stages
- Two live review sessions to walk through risks and ownership
- Final notes your team can keep after the engagement ends
Out of scope
We do not rewrite application frameworks, rebuild reporting warehouses, or provide ongoing staff augmentation. Cloud vendor selection and infrastructure provisioning stay with your operators.
Provider and process
Consultants from Service Riverbase lead the work from our Bangkok office, with remote sessions across Thailand when travel is unnecessary. Engagements open with a paid intake call, move into diagnosis, then into staged delivery with checkpoints you approve before any production cutover.
Timeline and delivery
Most flagship engagements land between three and six weeks depending on table count, foreign-key density, and whether dual-write periods are required. Work happens in your staging environment first; production cutovers are scheduled in quiet windows you choose.
Preparation
Before kickoff, share anonymized schema exports, recent slow-query samples, and a short list of business deadlines. Assign one engineer who can answer naming questions within one business day.
Constraints
We work with relational engines only on this engagement. If your primary store is a document database, ask about a limited advisory session instead.
Pricing basis
Pricing is quote-based after intake. We price against the number of hot tables, migration complexity, and review sessions requested. Deposits apply before script delivery begins; see the Rates page for typical ranges.
