Project Overview We have an existing Microsoft Access [Year2019/ 365] application currently split into a front-end and back-end. We need to migrate the back-end data to SQL Server Express to improve stability and multi-user performance. The front-end must remain in Access and be optimized to work efficiently with the new SQL back-end. Key Tasks & Responsibilities Database Migration: Upsize all tables from the Access .accdb/.mdb file to a SQL Server Express instance. Data Integrity: Ensure all primary keys, foreign keys, and relationships are correctly mapped and enforced in SQL Server. Table Linking: Use ODBC to link the Access front-end to the new SQL Server tables. Query Optimization: Identify and convert "heavy" Access queries into SQL Server Views or Stored Procedures (Pass-Through queries) to ensure the system doesn't lag. VBA Troubleshooting: Fix any existing VBA code that relies on DAO/ADO logic that might break after the migration. Security: Configure basic SQL Server permissions for 4 users. Technical Requirements Deep expertise in T-SQL and MS Access. Proven experience with ODBC connectivity and DSN-less connections. Strong understanding of linked table management and performance tuning. Ability to work via Remote Desktop or provide a migration script. Project Scope Total Tables: [70 tables] Total Records: [Largest table has 18 500 rows] Number of Users: 4

Hello, I understand you want a seamless migration from an Access (Year2019/365) front-end/back-end app to SQL Server Express while keeping the front-end in Access and boosting multi-user stability and performance. I’ve done similar migrations: upsize 70 tables with full keys and relationships, link the Access UI to SQL Server via DSN-less ODBC, and optimize by moving heavy queries into server-side views/stored procedures (pass-through). I’ll review and fix VBA (DAO/ADO) code to ensure compatibility with the new back-end, set up basic permissions for four users, and provide a clear cutover plan with testing. My approach is to map data types and constraints, stage data where needed, implement robust linking, and validate results with a focused test suite. I can deliver via a migration script or remote work, aiming for a 10-day execution window with milestones for schema migration, linking, query optimization, VBA fixes, security, and validation. Next steps: confirm SQL Server edition/credentials, and any security constraints, then I’ll share a detailed plan and timeline. Do you have a preferred SQL Server Express edition and hosting setup (on-premise vs. cloud) for the migration? Are there any security or compliance requirements beyond basic permissions for the four users? Should we use a DSN-less link from Access to SQL Server, or is DSN-based linking acceptable? Will you provide the SQL Server instance credentials and network access for the migration, or should I generate

Hi, I'm excited to bid on the project to migrate your Microsoft Access database from .accdb/.mdb files to SQL Server Express. With over a decade in the field, I've successfully completed similar projects and am confident in my ability to deliver high-quality results. The key tasks will include migrating 70 tables while ensuring data integrity through correct primary keys, foreign keys, and relationships. I'll use ODBC to link your Access front-end with SQL Server for efficient table linking. For query optimization, I’ll convert heavy Access queries into SQL Server Views or Stored Procedures to prevent system lag. My expertise in T-SQL and MS Access will be leveraged to fix any VBA code that may break during the migration process. Additionally, I'll configure basic SQL Server permissions for your four users to ensure secure access. I'm comfortable working via Remote Desktop or can provide a migration script if needed. You can check the portfolio on my profile for references. Best regards, Reed

Hello, I hope you are doing well. I'm a seasoned MS Access to SQL Server specialist, with deep expertise in T-SQL, ODBC connectivity, and front-end optimization. I’ve guided complex Access applications through full migrations to SQL Server, preserving data integrity and improving multi-user performance without sacrificing usability. Previously I upsized large schemas, accurately mapped PK/FK relationships, and switched heavy queries to SQL Server views and stored procedures to eliminate lag. I’ve also troubleshot VBA relying on DAO/ADO to keep business logic intact and prepared secure, simple DSN-less connections for linked tables. I can handle your 70-table, 18,500-row project for four users, either via Remote Desktop or with a migration script, and deliver a stable, responsive Access front-end backed by SQL Server Express. Please feel free to contact me so we can discuss more details. I am looking forward to the chance of working together. Best regards, Billy Bryan

Thanks for sharing the details. I’m confident I can handle this migration end-to-end and make sure your Access application runs faster, more stable, and multi-user safe on SQL Server Express—without disrupting your existing front-end workflow. I’ve worked on several Access → SQL Server upsizing projects with similar scale (50–100 tables, multi-user setups), where the key challenge is not just moving data, but preserving behavior and improving performance. My approach is careful and methodical: How I’ll handle your project Upsize all 70 tables to SQL Server Express using a controlled migration (not just the wizard), ensuring correct data types, indexes, PKs, FKs, and enforced relationships. Validate data integrity post-migration (row counts, constraints, orphan checks). Re-link the Access front-end using DSN-less ODBC connections for reliability and easier deployment. Review existing queries and identify “heavy” ones; convert them into SQL Views, Stored Procedures, or Pass-Through queries to eliminate lag and reduce network chatter. What you’ll get A stable SQL Server Express backend Faster multi-user performance Clean, documented setup (including connection strings) An Access front-end optimized for SQL, not just “made to work” I can work via Remote Desktop or provide scripts/documentation if preferred. Given your data size (18,500 max rows), this is well within a smooth, low-risk migration. Happy to discuss timeline and next steps when you’re ready.
