Cost Savings from AI-Accelerated Migration: A Model You Can Fill In

Project Economics, Not Licensing Arguments

This is about the cost of doing the migration — engineer-weeks, rework, elapsed calendar time. It is not a comparison of what you pay your database vendor. That decision is yours, it is usually already made by the time anyone reads a post like this, and it isn’t the part a migration tool affects.

Where a Migration Budget Goes

• Discovery. Building an accurate picture of what exists. Frequently underestimated because it feels like it should be quick.
• Schema and code conversion. The line item automation genuinely moves.
• Application changes. Embedded Oracle SQL, driver differences, ORM dialect settings. Usually the largest line, and mostly untouched by database tooling.
• Validation and UAT. Scales with defects found, not with data volume.
• Rehearsals and cutover. Each dress rehearsal costs a weekend of senior time.
• Rework. The line nobody budgets and everybody pays.

What Automation Changes

Honestly: two of those six meaningfully, and one of them enormously.

Discovery goes from weeks of spreadsheet archaeology to an afternoon, and the result is more accurate because it is measured rather than remembered. Conversion scales down to the flagged remainder. And rework — the unbudgeted line — shrinks in proportion to how many defects are caught before UAT, which is the single largest financial effect of good tooling and the hardest to see in advance.

Application changes, rehearsals and UAT are broadly unaffected. Any cost model that shows them dropping sharply is not modelling your project.

Fill in your own object count and your own blended rate. We are deliberately not putting currency figures in that table: our numbers would come from our benchmark and our assumptions, and a cost model is only useful when its inputs are yours.

Two Costs People Forget

Elapsed time has its own price. A migration running six months longer is six more months of running two systems, two backup regimes, and two on-call rotations. That cost is real and it is rarely in the spreadsheet.

Deleting beats converting. The cheapest object to migrate is one you decide not to move. A good assessment identifies the tables nothing has written to in two years and the columns that are entirely NULL — and the scope reduction from that is frequently larger than any efficiency gain from tooling.
