Quality Assurance Consulting: What a QA Maturity Assessment Actually Produces
This guide explains what a QA maturity assessment scores you against, what the deliverable looks like on the last day, and when advisory work is the wrong purchase.
Legacy System Modernization and Migration Services
Vervali modernises systems that still run the business: assessment of what the current system does and what it costs to keep, re-platforming or rebuild, data migration with reconciliation, and regression testing of the old and new systems against the same inputs so you can see they behave the same before you switch. Cutover happens with a rehearsed rollback in place.

How We Prove a Migration Is Safe
The buyer on this page has a system that still runs the business and is afraid of breaking it. US teams get this work in US hours, 9am to 1pm Eastern, with delivery from India, from an ISO/IEC 17025 accredited lab with CMMI Level 3 process. Four mechanisms sit at the top, not a transformation slogan: a parallel run, data reconciliation, regression comparison of old and new against the same inputs, and a rehearsed rollback that has been timed. The decision to abort is a decision, not a panic.
Cutover happens with that rollback in place. Book a modernization review if you already know the estate. A free assessment of one system is the first look.

01
Parallel Run and Regression
Both systems process the same inputs and the outputs are compared. Regression testing of the old and new against those inputs is how you see they behave the same before you switch. Method for that pass sits on application testing.

02
Reconciliation and Rehearsed Rollback
Counts and balances are signed before anyone cuts over. The rollback is timed in rehearsal, not invented on the night. If the comparison fails, you stay on the system that still works. That is the product of a modernization review.

Book a ReviewThe four approaches, and when each is right
Rehost, re-platform, refactor and rebuild. Each has a cost, a fix, and something it leaves behind. Rehosting fixes the hardware problem and none of the software problems. A lift and shift sold as modernisation is the most common disappointment in this market. We name the approach in the quote so you are not buying a rebuild under a rehost label.
Rehost and re-platform
Rehost moves the same software onto new infrastructure. Re-platform changes the runtime, the database or the hosting shape without rewriting the business rules. Cloud-native targets on AWS and Azure are the platforms Vervali builds on. The plan can name the clouds you already run. A lift to new hardware with the same defects still inside is not modernisation.
Refactor and rebuild
Refactor splits outdated applications using microservices, containers and a modern architecture so you improve agility without a full rewrite. Rebuild replaces the system. ERP, CRM and custom cores sit here when the old product cannot carry the next process. Cutover testing for those platforms sits with ERP and CRM development. A custom rebuild sits on custom software development.
Data migration and reconciliation
This is the part that actually goes wrong. Mapping fields where the old system's meaning is not the new system's meaning. Handling records that were never valid. Deciding what history moves and what is archived. Proving after the move that nothing was lost or duplicated.
The reconciliation report contains counts, balances, duplicates found, records that would not map, and the list of what was archived rather than moved. Backups and an audit trail sit in that pack. You sign that report before cutover, not after the first week in production.
Vendor lock-in and proprietary technology
When the legacy system runs on something the vendor no longer supports, or will not let you leave, the job is data extraction where there is no export, and rewriting the interface rather than the whole system. We do not pretend every closed box has a clean dump. What we could not see goes on the risk register. Open-source or a cloud target is a later choice, after the data you own is actually yours. A free assessment of one system is how we see that constraint.
Compliance and security after the move
A migration resets the evidence and an auditor will ask. Access control, audit logging, retention, and any certification scope the old system carried have to be re-established rather than assumed. GDPR and HIPAA are named when they apply to you. Vervali tests a client's systems for SOC 2 readiness and is not itself SOC 2 certified. ISO/IEC 27001 is the information-security management system we run. Detail and evidence packs sit on compliance testing when that pass is in the quote. Cloud execution of a move sits on cloud migration and modernisation and on cloud application development.
The cost of doing nothing
An ageing system costs money in maintenance, in the shrinking pool of people who can work on it, in the integrations it blocks, and in the compliance exposure of software that can no longer be patched. That is the shape of the internal case. We will not invent a typical savings percentage we cannot evidence. The quote after a free assessment of one system names what it costs to keep the current stack versus what the first move costs. Year two of doing nothing is still a number. It is just not on an invoice from us.
Proof from delivery, not a standalone-migration logo wall
Enterprise work from Vervali's records, by sector and country. The banking platforms and the operations platform. Migration work sat inside those jobs. They are not a claim that those were standalone legacy-only migrations.
India · two private-sector banks
60% faster loan processing and 50% less agent onboarding time, with the compliance the engagement required. Platforms like that do not move in one weekend. Assessment, a sequence, data that still balances, and a rollback you have timed are how a core that still runs the business is allowed to change.
60% faster loan processing 50% less agent onboarding timeIndia · manufacturer · operations platform
40% less manual stock reconciliation on a sales-operations platform. That is what changes when the old record and the new process finally agree. A cutover without that reconciliation is how month-end becomes a war room.

A system that still runs the business can also be costly to keep, hard to hire for, and unable to take the next integration or the next patch. Modernisation keeps the outcomes and drops the cost of keeping the old code. Assessment of what it does and what it costs to keep is the first look. Book a modernization review if you already know the estate. A free assessment of one system is how we start when you do not.
Rehost, re-platform, refactor and rebuild. Rehost moves the same software onto new infrastructure. Re-platform changes the runtime or hosting without rewriting the rules. Refactor splits the application. Rebuild replaces it. Rehosting fixes the hardware problem and none of the software problems. The quote names which one you are buying. A lift and shift sold as modernisation is the disappointment we refuse to label as done.
We do not sell a guarantee of zero disruption. We prove the move is safe before you switch: a parallel run, data reconciliation on counts and balances, regression comparison of old and new against the same inputs, and a rehearsed rollback that has been timed. The decision to abort is a decision, not a panic. Application testing is the method for that comparison.
The reconciliation report. Counts, balances, duplicates found, records that would not map, and what was archived rather than moved. Backups and an audit trail sit in that pack. You sign it before cutover. Field mapping is where the old meaning is not the new meaning. Invalid history is named, not silently dropped. That report is how you see the data arrived intact, not a go-live email.
Yes. Cloud-native targets are in the offer. AWS and Azure are the platforms Vervali builds on. The plan can name the clouds you already run. Rehosting onto a cloud account without changing the software is still a rehost. Cloud application development and cloud migration and modernisation are where that build sits if the quote includes it. A free assessment of one system is how we see whether the cloud move is the job or a later step.
Then the job is extraction where there is no export, and rewriting the interface rather than the whole system. We do not pretend every closed box has a clean dump. What we could not see goes on the risk register. Open-source or a cloud target is a later choice, after the data you own is actually yours. Book a modernization review once that constraint is written down.
Access control, audit logging, retention and any certification scope the old system carried have to be re-established. A migration resets the evidence and an auditor will ask. GDPR and HIPAA are named when they apply. Vervali tests a client's systems for SOC 2 readiness and is not itself SOC 2 certified. Compliance testing is the evidence pack when that pass is in the quote.
It follows the size of the estate, how much data moves, whether the approach is rehost or rebuild, and how long a parallel run must last before you will sign. We do not publish a fixed week count on this page. Time starts when we can see the system and the people who still know the batch. The quote after a free assessment of one system names the weeks. A larger core sits at the long end.
Price follows the approach, the data volume, the parallel-run window and the test pack. Clutch lists Vervali at $25 to $49 per hour. We quote after a modernization review or a free assessment of one system, not as a published project total. Doing nothing still costs maintenance, scarce skills and unpatched risk. That number is yours. The engagement number is the quote.
