Home/Modernization & Cloud/Database Migration
Database migration company
Database migration, done so your data arrives whole and proven correct.
Avaib moves your data to a modern, better-fitting database and verifies every step, reconciling counts and values on both sides so nothing is silently lost, truncated or corrupted. Minimal downtime, a way back at every stage, and a database you own outright.
Delivered for teams in Australia, the United States, Canada and the Middle East.
Your data, moved safely
Moving a database is easy. Moving it without breaking anything is not.
Database migration is the work of moving your data to a new home, a different engine, a supported version or the cloud, and reshaping it to fit so every record still lines up when it lands, and your first report on the new system reads exactly right.
The data you are moving is the memory of your business: years of customers, orders, records and history. So the fear is not really the move itself, it is what a bad move costs. Rows quietly lost or duplicated, dates and numbers mangled by a format mismatch, links between tables broken, a long outage while it happens, or a new database that crawls under real load. Worst of all, the kind of damage that does not announce itself until a report comes out wrong weeks later. A database migration is often part of a wider cloud migration or sits at the heart of a business intelligence project where clean, trusted data is everything.
Avaib does this the careful way. We profile your real data before we touch it, migrate in stages, and reconcile counts and actual values on both sides so a problem is caught and fixed before cut-over, not discovered after. The old database stays live until you sign off, so there is always a verified original to fall back on. Where your new database needs to talk to other systems, we handle the API integration as part of the same engagement. One accountable team, a database you own, at a cost-effective senior rate.
Not sure whether you need a database moved, a system replaced, or the whole thing modernized? That is the first, honest conversation we will have with you.

The database moves we handle most.
A migration is not always to the cloud. It is any move of your data to a better home, and these are the ones we do most often.
On-premise to the cloud
Move a database off your own servers to a managed cloud one on AWS, Azure or Google Cloud, so it is backed up, patched and scaled for you instead of by you.
One database engine to another
Move from an expensive or dead-end engine to a better-fitting one, for example Oracle or SQL Server to PostgreSQL, so licence costs fall and the platform has a future.
An old version to a supported one
Upgrade a database that is years out of support and out of security patches to a current, supported version, safely and without losing the data in it.
Many databases into one
Consolidate a sprawl of separate databases, spreadsheets and copies into one clean, single source of truth, so your reporting finally agrees with itself.
Into a new application
Move the data out of an old system and into the new one that is replacing it, mapped and reshaped to fit, so the new application starts life with your real history intact.
Into a reporting or data warehouse
Copy operational data into a warehouse or analytics store built for reporting, so heavy queries stop slowing the system your business runs on.

The silent corruption trap, and how we keep you out of it.
The most dangerous migration failure is not the one that errors and stops. It is the one that reports success while quietly breaking your data. Here is how it happens.
The migration reports success
Every row moves, the job finishes green, and on the surface the new database looks full and correct. Everyone breathes out and switches over.
But the data is quietly wrong
A date format flipped, a number lost its decimals, a text field was truncated, or a link between two tables broke. Nothing errored, so nothing warned you.
And you find out weeks later
A report comes out wrong, an invoice is off, a customer record points at the wrong account, and by then the old system is gone and the bad data is your only data.
Our answer is to never trust a green checkmark on its own. We reconcile counts and totals and compare the actual values on both sides, so silent damage is caught on a rehearsal, before your real data depends on it, and never becomes the problem you find out about weeks too late.
Proven, not assumed
How we prove every record survived the move.
Verification is the heart of how we migrate, not a tick-box at the end. These are the checks that turn "the data moved" into "the data is correct".
We profile the source first
Before moving anything, we examine the real data, its formats, ranges, duplicates and oddities, so we migrate what is actually there, not what the schema claims.
We reconcile row counts and totals
After each stage we count records and sum key figures on both sides and check they match, so a row that vanished or doubled is caught immediately, not in a report months later.
We check the values, not just the volume
We sample and compare actual field values across the two databases, so a silently mangled date, a truncated field or a broken relationship is found and fixed before cut-over.
We keep the source until you sign off
The old database stays live and untouched until you have confirmed the new one is right, so there is always a verified original to fall back on and compare against.
The fears, answered
What worries people about a database move, and how we handle it.
These are the real concerns we hear before a migration starts. Here is exactly how Avaib takes each one off the table.
Why Avaib
Why choose Avaib for your database migration.
Most providers can offer one or two of these. Our whole model is built to give you all of them at once.
Verified, not just transferred
We reconcile counts, totals and actual values on both sides at every stage, so your data is proven correct in the new database, not merely assumed to have arrived.
Minimal-downtime cut-overs
We sync the new database alongside your live one and switch over in a short, planned window, so the business keeps running instead of stopping for the weekend.
Safe by design, with a way back
The source database stays live and untouched until you sign off, data is encrypted in transit and at rest, and there is always a verified original to fall back on.
Senior expertise, without the premium price tag
The same capability Australian, US, Canadian and Middle-East firms charge a fortune for, delivered by senior database engineers who have done real migrations, from around USD 25 per hour.
AI-accelerated delivery
Our senior engineers use advanced AI coding tools to move faster through schema mapping and the migration scripts, directing and reviewing every step, so you get speed without cut corners.
You own it, with a real QA team behind it
The migrated database and its data are yours with no lock-in, every stage is checked by a dedicated QA department, and a 30-day warranty means we are still here after cut-over.

A safe path from your old database to a verified new one.
Profile the source, map and transform, dry-run and reconcile, sync in parallel, then a verified cut-over. No blind copy, no long outage.
Profile the source
We examine the real data, its formats, sizes, duplicates and quirks, and map how the tables relate, so the plan is built on what is actually there, not on what the schema promises.
Map and transform
We design the target schema and the rules that reshape every field to fit it, handling date formats, data types, encodings and relationships deliberately instead of hoping they line up.
Dry-run and reconcile
We run the migration on a copy, then count records and compare values on both sides to catch anything lost, doubled or mangled, and fix the mapping until the two databases agree.
Sync in parallel
We keep the new database up to date alongside the live one, so when it is time to switch there is no long freeze and no scramble to catch up on changes made during the move.
Cut over and verify
We switch over in a short, planned window, run the final reconciliation, and keep the old database available until you have confirmed the new one is right, then support it under a 30-day warranty.
Pricing
Enterprise-grade migration, without the enterprise price tag.
The same capability Australian, US, Canadian and Middle-East firms charge a fortune for, delivered by senior database engineering from around USD 25 per hour, at a fraction of the price. You pick the engagement model that fits, and every one is built by senior specialists and owned outright by you.
Migration assessment
A small, fixed engagement that profiles your source database, checks its data quality, and returns a costed migration plan with the real risks named, so you decide with facts, not guesswork.
Fixed-price migration
An agreed price, timeline and plan to migrate a defined database, with reconciliation and a verified cut-over built in, ideal once the assessment has set the scope.

Common questions
Database migration, answered.
What is database migration?
Database migration is the work of moving data from one database to another, for example from your own servers to the cloud, from one database engine to a better-fitting one, from an old version to a supported one, or out of an old system and into the software replacing it. It usually means more than a straight copy: the data has to be mapped and reshaped so it fits the new structure, and then checked to make sure nothing was lost or altered along the way.
Done well, a migration is verified, not just transferred. The data is profiled first, moved in stages, and reconciled on both sides so counts and values match, while the old database stays available until the new one is confirmed correct. Avaib has delivered software and data across more than 600 projects since 2004 and applies that same discipline to every database it moves.
How do you make sure no data is lost or corrupted?
We treat verification as the heart of the job, not a final tick-box. Before we move anything we profile the real source data, then migrate in stages and reconcile row counts and key totals on both sides so a record that vanishes or doubles is caught at once.
We also compare the actual field values, not just the volume, because the dangerous failures are silent: a date format that flipped, a number that lost its decimals, a text field that was truncated, or a link between tables that broke. We find and fix those before cut-over, and keep the source database untouched until you have signed off.
Will our systems be offline during the migration?
For most migrations there is little or no downtime. We build and populate the new database alongside your live one and keep it in sync, so the business keeps running while the work happens.
When it is time to switch over, we do it in a short, planned window at a quiet time, after the data has been reconciled and verified. A carefully staged cut-over, not a long weekend offline.
Can you migrate between different database engines, like Oracle to PostgreSQL?
Yes. Moving between engines, for example Oracle or SQL Server to PostgreSQL or MySQL, is one of the most common reasons businesses come to us, usually to escape rising licence costs or a platform with no future.
These moves need care because the engines differ in data types, functions and behaviour, so we map every difference deliberately and test the result, rather than relying on an automatic tool to get it perfectly right. You end up on an open, portable engine you own, without the licence bill.
What happens if the migration goes wrong?
It should not, because we dry-run the migration on a copy and reconcile it before touching production, so problems are found and fixed on a rehearsal, not on your live data.
And if anything is not right at cut-over, we can go back. The source database stays live and untouched until you have confirmed the new one is correct, so there is always a verified original to fall back on. We never burn the bridge behind you.
How much do database migration services cost?
It depends on how large and complex the database is, how many systems depend on it, and how much the data has to be reshaped to fit the target. A fixed migration assessment is a small, low-risk first step, while moving a large, busy database is a bigger engagement. Avaib's model is senior expertise at a cost-effective rate, typically around USD 25 per hour, which is why businesses in Australia, the US, Canada and the Middle East work with us instead of paying big-firm prices.
Tell us about the database you need to move and where you want it, and we will propose a right-sized engagement with a clear scope and a ballpark price, plus a free, no-obligation written estimate after a short scoping conversation.
How long does a database migration take?
It ranges from a couple of weeks for a focused, well-understood database to a few months for a large one with messy data and many dependent systems. The honest timeline comes after we profile the source and see what we are really dealing with.
Because we sync the new database in parallel and cut over in a short window, you are not waiting on one big offline event. You see the plan, the dry-run results and the reconciliation as we go, so the timeline stays something you can check.
Do we own the migrated database and its data?
Yes. The migrated database, its data and its cloud accounts are entirely yours. There is no per-seat licence to Avaib and no lock-in to keep it running.
Where it fits, we favour open, portable engines like PostgreSQL precisely so you are never trapped by licensing again, and you are free to take the database to another team at any time.
