As the volume of data and number of users in an Access database increases, then to get better reliability and performance it is a great idea to move the data into SQL Server. The existing Access desktop database, can then be re-linked to the data in SQL Server. Having converted over 50 systems in the last 10 years, I can offer a great deal of expertise in over-coming difficulties when migrating data, planning security and using schemas to improve the manageability of the design. The services that I offer are based around Microsoft Access and SQL Server. Some of these services are based around using a product called the Migration Upsizing SQL Tool (MUST), which has been successfully sold internationally to over 200 companies, www.upsizing.co.uk
