ABCloudz can help you migrate Oracle to SQL Server achieving the performance, scale, and security of your mission-critical applications on-premises or in the cloud.
Many Oracle customers are concerned about being locked into a single vendor with high licensing costs. Very often they realize this fear when the time to upgrade or modernize their environment comes.
Using Microsoft SQL Server, ABCloudz can help Oracle customers achieve the performance, scale, and security that their applications require while keeping costs under control.
Microsoft SQL Server reduces costs by consolidating databases, virtualizing servers, compressing data, allocating resources more effectively, and managing policies. ABCloudz can help you utilize SQL Server’s self-service business intelligence capabilities. As a result, this provides end-users with the ability to create their own ad-hoc reporting. So, organizations can significantly reduce their dependency on IT.
Database migration is a daunting task with a lot of hidden issues and possible problems. With our extensive experience, we can overcome most of the database migration challenges.

Checking the database performance after migration |
Prior to the migration, you should have a good understanding of your database workload including any key performance metrics and frequency of peak loads. The key to a proper comparison is a mechanism to replay a workload. You can achieve this through the SQL Server Distributed Replay feature or your own load harness. Once under load, you can evaluate your new technology by monitoring pressure on CPU, Memory, IO Operations, and network traffic. By monitoring when the system is under pressure you can determine if your technology is properly sized. Also, you can figure out that you need to adjust resources. ABCloudz can help you profile your existing environment and then grade your migration against that profile. |

Migrating indexes from Oracle to Microsoft SQL Server |
At first glance, an index is just another object in the database that needs to be migrated. However, the manner in which data sits in storage is very different between Oracle and SQL Server. ABCloudz approaches this circumstance by examining the logical layout of the tables and relationships, paying special consideration to the business needs and use cases of the underlying data to determine an appropriate indexing strategy. |
|
Licensing optimization |
One of the major factors to be considered when we migrate Oracle to SQL Server is licensing. In most cases, a SQL Server Standard edition may suffice. However, there are some key features of Enterprise Edition that you should consider because they may have a big impact on the security, availability, manageability, and performance of your workload. |
|
Oracle to SQL Server conversion scope |
When it comes to scope there is a choice that must be made around how the conversion will proceed. Then the team will review all the source Oracle schemas. After that, we can either migrate each schema into its own isolated database or convert it into a single database with multiple schemas. Also, we will work with you to consider the required security for isolation needs between the various schemas. |
|
Specific migration issues |
There are several considerations for migrating an Oracle database. In addition to reviewing the schemas in each Oracle instance, you need to pay special attention to data type differences and incompatibilities. For example, numeric and date/time values are stored at different levels of precision and scale. Moreover, Oracle and Microsoft implement the SQL ANSI standards differently which may return different results. |
|
Testing the converted code |
It’s paramount that a QA team that is familiar with business needs and with the data review the code conversions from Oracle to SQL Server. Moreover, the QA team will need to verify that the converted code returns the expected data in the format and order that the business is accustomed to. |
Sometimes you need a helping hand to get you started. For example, here are some of our offers to help with assessments, using SSMA, or developing a future-state roadmap.
We start with assessing your on-premises Oracle data environment. At the beginning of a project, you discuss existing database deployments and tools with a dedicated ABCloudz project team. This step helps establish the information, resources, and team members needed from your side.
You then make your data infrastructure available to trusted ABCloudz team members. We use this access to identify issues and craft a modernization path that fits within your current environment.
Our proficient solutions architects then design the future-state architecture of your data environment. Our experienced team can provide you with comprehensive technical and financial information about the potential pros and cons of any proposed modernization project.
What makes ABCloudz different from other service companies is that we provide you with human resources to address these modernization tasks.
“Low-performing and costly” – these were major characteristics of the Oracle system for one of our customers, a leading US automotive manufacturer. In this regard, it was quite natural for them to consider migration to another database platform. We suggested changing their Oracle Database to Azure SQL Database and also moving their applications to Azure.
Our experts calculated that the customer can to save approximately 1 million dollars over the next 5 years based just on reduced licensing!
