Migrating a Lie Science database into the cloud

Brief description

As part of a planned standard software retirement the customer would like to migrate their application data from an existing Oracle database (on-premise) to a cloud database. The scope of this project is to set up and execute an automated database migration with target system Azure PostgreSQL. In a second phase, changes will made to the business data model and the application data.

Supplement

The integrity of the data is the most important factor in the migration, meaning that thorough testing is crucial. The ora2pg tool provides options to compare the original and the target database schemata. Microsoft also offers a tool (the -Database Compare Utility-) that can be used to verify the results in the target database based on the original. The customer's long-term strategy is to move their historical data into the cloud. For the current use case (storage of application data), we recommend an Azure PostgreSQL instance because it offers low cost and high flexibility.

Subject description

The customer used the database to store development test data generated during the development and approval of biopharmaceuticals. The original application and its datastore (Oracle on-premise) are no longer required, but the data itself is still relevant for legal reasons. After the migration, the customer plans to make technical changes to the data model and the data so that it can be queried effectively as part of an archive search
