Maintaining and running IT infrastructure in a cost-optimized way is the goal of almost all organizations in the modern data-driven business environment. The focus is on using databases that are not only technologically advanced with cutting-edge features but also do not heavily impact profitability and the bottomline. One way to do so that has been beneficial for enterprises cutting across sectors and industries is Oracle to SQL Server migration of databases.
Consider the Oracle database first. Users working on this platform have to pay, apart from the usual license charges, additional fees for partitioning a table. Also, more fees are payable for using a few other advanced features like Database Encryption and Dynamic Data Masking.
Next, switch to the Microsoft SQL Server. All these features of Oracle as mentioned come as standard and are available out of the box in the Microsoft SQL Server Enterprise Edition. This results in massive savings for those on SQL Sever leading businesses to choose Oracle to SQL Server migration. To make things easier, SQL Server offers special tools like the SQL Server Migration Assistant (SSMA) for database migration that is free across all editions.
What then are some of the benefits of Oracle to SQL Server migration?
- Lower licensing cost is not the only reason for Oracle to SQL Server migration. There are several other avenues through which costs are kept under control by SQL Server. These include visualization of servers, data consolidation, and data compression. The data compression facility apart from saving on storage and reducing costs also leads to higher database performance.
- For traditional databases, installation entails downloading additional drivers and applications. On the other hand, SQL Server can be quickly and seamlessly installed with a Setup Wizard without using any command-line configuration. After installation, all upgrades are downloaded automatically without human intervention.
- Data safety and security is one of the critical benefits of SQL Server and one of the key reasons why businesses opt for database Oracle to SQL Server migration. The complex and encrypted algorithms of SQL Server ensure that no unauthorized person can hack into the database. Further, a network of strict permission and access management programs keeps classified business data insulated from any unwanted intrusions.
- A very critical advantage provided by the SQL Server is the capability to restore and recover damaged and corrupted databases. The process works in the following manner. The functioning of the SQL Server database engine enables data storage and running queries by users via indexes, files, and transactions. Before committing to a transaction, log records are updated on the disk. Therefore, in the event of an outage or a crash of the operating systems, transaction logs are issued by the instance. Once the problem is overcome, the logs work to restore the incomplete transactions right to the point where the outage took place. Any loss of data is thereby avoided.
- SQL Server has several editions. Businesses can choose one that not only matches their need but also meets their budgetary limitations. For example, the most expensive is the Enterprise edition that is suitable for large organizations and is available with many advanced features. Small and mid-sized enterprises on a budget can opt for the Standard edition with a lesser number of capabilities at lower costs. Finally, there is the Express edition that is free but has very limited features. It is ideal for start-ups and individuals. Apart from these platforms, SQL Server has the Developer SQL Server version used primarily by developers to test their work on the SQL Server.
These are some of the benefits of Oracle to SQL Server migration.
Now, what process do businesses have to follow for successful Oracle to SQL Server migration?
Before going into the actual Oracle to SQL Server migration process, a few preliminary steps have to be implemented.
- SQL Server is to be first installed in the target database where the data is to be moved. Proper connections have to be established between the Oracle source database and the SQL Server target database. Further, it is necessary to install both SQL Server Migration Assistant and Oracle Client in the target database.
- All firewall issues need to be resolved before migration and proper connectivity is to be ensured with the port before SSMA is launched and linked with the source database.
- The target database has to be mapped with the Oracle schema where Oracle to SQL Server migration is to be done.
- Finally, Oracle database objects are to be converted and loaded to the SQL Server. This can be done in one of the two ways – saving a script and applying it on the SQL Server or after synchronizing all database objects.
These activities have to be done also when migrating databases from Oracle to Azure SQL database and Azure Synapse Analytics.
The ground is now ready for Oracle to SQL Server migration and here there are two ways to do it.
In the first instance, the migration is a one-shot process completed without a break. The source database is shut down as all transactions completed after the last backup orthe last run will otherwise not move to the target database.

On the other, the stagnant data and the less-used data are first moved to the target after which all changes made at the source databases are continually uploaded in the target database in pre-set intervals.
