There are four major areas of concern when migrating a database from dialect 1 to dialect 3:

  • Double quotes
  • The DATE data type
  • Large exact numerics (for purposes of this discussion, NUMERIC and DECIMAL data types that have a precision greater than 9)
  • Keywords

The process varies somewhat depending on whether you can create an application to move data from your original database to an empty dialect 3 database. If you do not have access to such a utility, you need to perform an in-place migration of the original database.
