Oracle database customers are often concerned about using a database server with high licensing costs. Using other database servers like Azure SQL allows former Oracle customers to obtain the scale, performance, and security that their applications need at a relatively lower cost. An oracle database migration is seldom a straight forward process. However, if you need to upgrade your electronic health record system to improve the quality of care and drive down costs, you may need to migrate from your Oracle database. You want to do this with minimal downtime and without any loss of data or violation of data privacy laws. Here are some expert tips for a stress-free oracle migration:

1. Study the Database Performance

Many migration clients complain that their current database is slow during peak load periods. Before migration, understand the frequency of your peak loads and key performance metrics. You can simulate the workload using SQL Server tools. While the workload replay is on, you have an opportunity to monitor essential metrics like CPU and memory usage, network traffic, and input/output operations. Monitoring the system while it’s under pressure allows you to discover if your present hardware and network profile is adequate for your current and future operational needs.

2. Choose the Most Appropriate License

Licensing is a significant factor to consider when migrating from Oracle to SQL. SQL Server comes with a standard and an enterprise edition. For small healthcare providers with a single location, a standard license may be sufficient. However, providers with multiple locations with massive network traffic should use the enterprise edition. An enterprise edition license will provide better data security, server availability, performance tuning. It is also easier to scale up as the organization grows.

3. Optimize Indexes During Migration

Ordinarily, a database index is an object that boosts database performance. However, indexes are stored and used differently in Oracle databases and SQL Server. That’s why it is essential to examine the tables, their primary keys, and the relationships that join them together. Then review business needs and all the use cases, for the data retrieval and storage, before creating an optimal indexing strategy in the new database.

4. Pay Attention to Database Incompatibilities

There are essential differences in database implementation for consideration during an Oracle migration. Apart from reviewing the schemas in the Oracle database, you must focus on data type differences.

For instance, numeric and date/time values are stored with different precision levels. Similarly, the implementation of SQL ANSI standards is not compatible with Oracle and SQL Server. These issues may lead to a difference in results after migration.

5. Test the Code After Conversion

For a successful Oracle migration, you need to build a team of QA experts familiar with critical data capture and retrieval scenarios. This team will be responsible for reviewing applications and reports that depend on the database. The QA team will verify the converted code and ensure that it returns the required data in the desired format.
