Access to SQL Server Migration: Fixed Scope, Familiar Screens

This page is for teams that want a defined migration project: assessment, written scope, fixed price, cutover and hypercare. We keep the Access front end when staff still need those screens, and we do not force a full application rewrite to fix a file-based backend. If you still need a keep-or-move decision before scoping a migration, start with our MS Access consultant review.

Fixed-scope project estimates based on the business value we deliver. Projects typically start at $1,200 - smaller fixes can be less, larger systems more.

Every corruption event threatens orders and inventory. Every slow report is staff waiting instead of shipping. In our documented distributor migration case study, a 1.8 GB Access file on a network share for 25 users meant roughly 20 hours a week lost to waits, retries and repair cycles until the backend moved to SQL Server while the Access UI stayed.

We provide fixed-cost project estimates based on the business value we deliver. Projects typically start at $1,200, though smaller fixes are often less and larger systems cost more. After a free review, you receive a written scope and fixed quote - not an open-ended hourly bill. Simple fixes are quoted as small packages; custom databases, migrations, and automation systems are scoped as fixed projects after we review your requirements.

Five things move the price:

The number in your quote is the number you pay for that scope. If your needs change, we agree the change in writing before any work starts. Hosting fees, if any, are separate.

In a normal upsizing project the tables move to SQL Server, and the Access forms, reports and code stay where they are, pointed at the server through linked tables. Staff open the same front end and see the same screens. What changes underneath: the 2 GB ceiling disappears, concurrent users stop fighting over one file, a dropped connection no longer risks the data file, and backups become something the server does.

Some work is always scoped up front: queries that assumed a local file need rewriting so the server filters the data, and a few forms bound to whole tables may need tightening. A full rebuild as a web application is a separate decision. If you are still weighing optimize vs upsize vs rebuild, get that call in writing on the MS Access consultant page before you buy a migration.

Moving off a shared Access file is the decision. Where the data lands is a second, smaller decision.

Best when everyone works from one or two offices and you already have a server and someone who looks after it. Lowest latency for on-site staff, full control of backups, no ongoing cloud bill. Remote workers still need a VPN or remote desktop.

Best when staff are spread across locations or work from home. The database is reachable without pushing a file share across a VPN. You trade a monthly cost and a dependency on internet connectivity.

Often the fastest way to stop corruption this month: Access and the data both live on a server, and staff connect to a session. It does not remove the 2 GB ceiling or raise concurrency much, so treat it as stabilization rather than the destination.

For: teams whose Access UI still works but whose file-based backend is the risk—size, users, speed or corruption—and who want a fixed-scope delivery project.

Not for: brand-new systems with no Access yet (see Create Custom Access Database), schema redesign without upsizing (see Access Database Design and Development), or DIY how-to guidance alone—if you only need a keep-or-move recommendation, use MS Access consultant.
