Database migrations are a core-competency at PCA, and our engineers are expert at evaluating source database systems which you are having problems with or have outgrown, and determining the essential steps necessary to successfully migrate your existing data management system to a more stable and scalable solution.

	Excel to MS Access	As the amount of data in your MS Excel spreadsheets grows or becomes more critical in nature, it can become increasingly risky to avoid migrating to a database to properly store and constrain your business information.  For smaller LAN-based use with a limited number of users, migrating your MS Excel spreadsheet(s) to MS Access may provide an adequate, cost-effective approach.

	Excel to SQL Server	While Excel spreadsheets offer a lot of power to users and can be quickly shared and updated, keeping data constrained and properly tracking changes in a multi-user environment can easily get out of control.  If you have run out of columns or rows in your excel spreadsheet, find it impossible to track changes to data, or are continually cleaning-up missing or invalid data, then it is probably time to consider migrating to a real enterprise-level database solution.

	MS Access to MSDE	If the amount of business data and/or end users has outgrow the limitations of MS Access, but you do not require the Internet database connectivity that a full SQL Server license affords, migrating your MS Access data store to the Microsoft SQL Server Desktop Engine (MSDE, aka SQL Express) might be the right solution. This approach overcomes many of the performance, security and scalability deficiencies of MS Access, while preserving your investment in the MS Access front-end application.

	MS Access to SQL Server	Upgrading from MS Access to SQL Server can pose many challenges, usually related to data corruption and lack of data integrity constraints. PCA has the experience and skills to successfully navigate many of the obstacles that typically block efforts to migrate data from an intro-level MS Access database to a commercial-strength SQL Server database.

Migrations from legacy database platforms can present significant challenges in terms of the quality and completeness of the source database schema, constraints, referential integrity, and more.   In addtion, the engineering techniques and methods can vary widely from one database system to the other.  Migrating to SQL Server often requires a data schema redesign for optimal data integrity, security and performance.  Cleaning up legacy data quality issues is also frequently part of the database migration effort.  Our experience solving many of the common (and uncommon!) issues that can arise during database migrations have made our process both thorough and efficient.
