We propose the best option from complex data migration methods

There is a wide range of migration methods for Oracle database such as the old exp/imp method, Data Pump, portable table areas, and Golden Gate. With each successive version, data migration options are becoming more complex, and it is difficult to determine which migration method is the best option. Problems with the database that stores the fundamental data of business operations directly lead to problems with core operations, so it is important to be able to "migrate without any problem in a short period of time with minimal risk.

We offer a variety of migration methods to meet the customer system specifications and requirements. (*This service is based on the Data Pump, but please feel free to contact us for other methods.)

Data difference and integration with other systems

It is also necessary to check for consistency issues with the migrated data in addition to considering the migration method. For example, we have seen cases where differences are found when the number of data records and the contents of the actual data are compared before and after the migration and in fact, procedures that must be considered have been overlooked. If the databases are linked from other databases by DBLink, it is also important to note that there is a risk of operation suspension if the order of migration is not organized.
