Migrate from Microsoft Access to a Web Application
Replace your desktop-bound Access database with a cloud-accessible web application — multi-user, secure, and available anywhere.
Migration: Access to Web App
From Microsoft Access to Custom Web Application
Why Migrate
- Cloud Access: Access databases are trapped on desktops or file shares. Web applications are accessible from any device, anywhere, with real-time collaboration.
- Multi-User Scalability: Access struggles beyond 10 concurrent users and 2GB file size. Web applications scale to thousands of users with millions of records.
- Modern Security: Replace file-share security with role-based access control, encryption, audit logs, and SSO integration.
Migration Roadmap
- Access Database Audit (1–2 weeks): Catalog all Access tables, queries, forms, reports, macros, and VBA modules. Design the PostgreSQL schema.
- Table and relationship inventory
- Query conversion plan
- Form and report catalog
- Application Build (4–8 weeks): Build the web application with equivalent forms, queries, and reports. Migrate VBA logic to server-side code.
- Web application with all forms
- Converted queries and reports
- Business logic migration
- Data Migration (1–2 weeks): Export Access data to PostgreSQL, validate referential integrity, and run parallel testing with users.
- Migrated database
- Data validation report
- User acceptance testing
Risks & Mitigation
- Complex VBA macros are difficult to convert: We analyze each VBA module and rewrite as server-side TypeScript with unit tests validating output parity for all business logic.
- Users depend on Access-specific report layouts: We recreate critical reports as web views with PDF export, matching the layout and data presentation users rely on.
Estimated Scope
Hours: 160–320 | Cost: $320–$640 | Timeline: 6–12 weeks
Frequently Asked Questions
- Can you replicate our Access forms?
- Yes. We rebuild all forms as responsive web interfaces with the same data entry workflow, validation rules, and lookup fields.
- What happens to our Access queries?
- Access queries are converted to PostgreSQL views and stored procedures, often with better performance and additional capabilities.
- Can we still generate the same reports?
- Yes. We rebuild Access reports as web-based views with filtering, sorting, and PDF export matching your current report layouts.
