The best solution should never be determined by what's the easiest way to migrate something. You have to think long range. It may be marginaly more difficult to move to an Informix database, but you'll get a better engine to run your application on. That's long range thinking. One day you'll possibly also want to move away from MS Access as a front end tool. It's fine for small things, but it definitely have it's limitations. Even using Visual Basic would be much better. Moving the application from MS Access to Visual basic, probably a pease at a time, may not be too hard. You may retain reports and some other things in MS Access, but create your user interface in Visual Basic. As your database grows you may also find it advantageous to create server side applications or even multi tier applications. At that time you should take a hard look at Java for development. That's the time you sure want to leave Microsoft behind. They haven't done anything worthwhile with or in Java. At that time another engine may also prove a significant advantage. Using Informix you will even have the option of going to the Universal Server Option giving you significant advantages at the engine side.
