When to call me

Unclear risk

The migration scope is still fuzzy

You need someone to separate real risks from assumptions before timelines, budget and downtime promises become locked in.

Readiness assessment
Dependency mapping
Risk register

AWS tooling

DMS/SCT design needs review

Tool choice, task design, full-load/CDC posture, validation queries and rollback planning need experienced review before production migration.

After migration

Performance and operations need hardening

A successful migration still needs query tuning, indexing, vacuum/maintenance posture, monitoring, backups and operational handover.

Delivery focus

Assessment

Know what you are moving

Source platform behaviour, data volume, schema complexity, integrations, jobs, replication and business criticality.

Stakeholder summary

Best-fit engagement

Usually starts with a short readiness assessment, then expands only if the risk profile and business case justify a delivery engagement.

Migration success criteria I look for

Business continuity

The migration plan should make downtime, data validation, rollback and customer impact explicit before execution starts.

Operational readiness

The target platform needs monitoring, backup/restore, access, support runbooks and ownership, not just a successful load of data.

Performance after cutover

Query plans, indexes, parameters and maintenance tasks must be checked early so the new platform does not become a slower version of the old one.
