Preserving Recnum During Migration
Monday, February 25th, 2008The Use Regular Save During Migration (SQL Server only) means that when it is checked, SQL puts recnum in sequence on backend which meaning they won’t match the sequence from DataFlex. If the option is on, then the recnum will follow the DataFlex sequence on the backend. When this option is on, the migration takes longer. Flex2SQL contains facilities for high-speed data migration, including generating SQL*Loader scripts and text files for Oracle and bulk copying of data to MS SQL Server, making it easier to transfer very large databases with both drivers. The SQL scripts enable you to create tables and indexes outside the tool. The high-speed data migration is the default option.
