THE MIGRAVEN PRINCIPLE

A result is only useful when the reviewer can trace it back to the records and rules that produced it.

M / V
01 / WHO IT IS FOR

For teams accountable
at migration sign-off.

For ERP and CRM implementation consultancies, migration delivery leads and data-assurance teams that must explain what changed before a checkpoint or client sign-off.

01
↗

Implementation consultancies

Give delivery leads a consistent way to inspect agreed source-to-target exports across client engagements.

DELIVERY PARTNERS
02
⌘

ERP & CRM migration teams

Make selected record checks easier to repeat, review and explain at each migration checkpoint.

Data assurance reviewers

Receive an exception register with field-level differences and original row references for follow-up.

QUALITY & ASSURANCE
02 / WHAT IT DOES

Two exports in.
A clearer review out.

Migraven does not move or transform records. It verifies the agreed values after a migration or test run.

LOCAL EXECUTIONDETERMINISTIC RULESHUMAN SIGN-OFF
03 / WHY IT MATTERS

A clearer checkpoint.
A defensible review trail.

Turn a defined export pair into a repeatable review: selected fields, explicit comparison rules, traceable findings and a human decision on every exception.

01

Find the exception faster

Bring unequal values and one-sided keys into a focused worklist instead of searching two exports manually.

02

Keep the context attached

Every finding carries the comparison key, values and source-row references needed to investigate.

03

Repeat the same rule

Use explicit keys and fields. Avoid hidden assumptions about dates, numbers, currencies or business meaning.

04

Preserve a review package

Keep machine-readable results, a self-contained report and hashes that help detect later file changes.

04 / SEE IT WORK

Don't take the diagram
on trust.

Run a live comparison in your browser with synthetic records. Change the selected key or fields, inspect the exceptions and export the result. Your files stay in your browser.

05 / A COMMERCIAL PATH THAT SCALES

Start with one checkpoint.
Expand on evidence.

Start with one active migration checkpoint. If the evidence package improves the review, extend the workflow across projects and delivery teams.

ENTRY

Paid evaluation

A scoped export pair, agreed fields, evidence package and reviewer walkthrough.

REPEAT

Team licence

Repeatable use across a migration team, subject to commercial licensing and support terms.

EXPAND

Partner programme

Consultancy-level deployment and repeat engagements under negotiated terms.

Commercial terms, licensing, payment collection and customer data agreements must be finalised before production engagements. No subscription or payment processing is currently represented as live.

THE NEXT CHECKPOINT

Make the evidence
part of the process.

For migration consultancies and teams with an upcoming checkpoint. Start with a synthetic or de-identified sample.
