IBM officially no longer supports DB2 version 11.50 since April 2018 and support for version 11.70 will cease to exist on September 30, 2020. DIGICORP performs the Complete Migration Process of its Database DB2 for versions 12.10 or 14.10, ensuring that your systems operate safely and with guaranteed support.
Before migrating your IBM DB2 Database, we gather diagnostic information, especially if your applications are large and complex. Diagnostic information is important to verify the behavior of the Database server after migration and also if further support is required.
After collecting the necessary information and making the diagnosis with the collected data, we create backups of your IBM DB2 Databases according to the characteristics and complexity of your systems, in order to allow the subsequent import of the data and a process rollback and restoration should any problem occur during Migration.
The migration of your IBM DB2 Database will use the test and production hardware of the new machines or environments, so the operating system installed on these computers must be compatible with the version of DB2 that will be migrated, and there must also be enough space so that data can be saved successfully.
After proper preparation of the operating systems and hardware on the new machines or environments, the installation of the selected version of the IBM DB2 Database will be performed. To save space, only the necessary components of the installation will be selected, according to the characteristics of your application.
Based on the architecture and structure of your existing DB2 Databases, we created the new Databases required for the proper functioning of your application, using the settings referring to the version of the installed software and the hardware and operating systems of machine that will support the new instance.
The necessary configuration for your IBM DB2 Database will be defined, creating all the necessary configuration files, in order to ensure that the desired data structure and relationship is consistent. We’ve also added new parameters to the settings in case any architecture changes are needed to ensure compatibility with the new machine and operating systems.
Based on the existing databases' schemas and relationships, we apply the appropriate configurations to the new DB2 databases created to define the data structure and dependencies between the information, making changes if necessary to ensure compatibility with the new installed version.
A monitored process of importing and transferring data already existing in your IBM DB2 Database will be initiated, in order to make it available in the instance of the new version and ensure the consistency of the information.
After all the previous steps have been performed, the installed version of your IBM DB2 Database will be initialized and a series of consistency, integrity and performance tests will be carried out, in order to verify whether the migration process was successful and whether the running instance is working as expected.
Continuous monitoring of the new IBM DB2 Database will be carried out after the Migration, in order to detect any anomalies, performance problems and data inconsistencies. If there are errors, DB2 Migration Statistics will be collected and the necessary corrections will be applied to guarantee the success of the Migration process.
