Database Migration – What You Need To Know Before You Start

Database migration is an essential process for businesses to migrate data from the source database to a target database. Companies use database migration services to perform the task efficiently, accurately, and cost-effectively. 

Once you complete the migration, the dataset from your source database is restructured and reorganized in the target data. There are a few things to consider before migrating your database to the cloud. Read on! 

Source Database Architecture 

Migration of your source database to the cloud is not an easy task. It requires careful planning and preparation. First, you have to consider and analyze your source database architecture. For example, a heterogeneous migration requires changing the controls because the source and migration databases are two different environments. 

Therefore, you have to change the controls based on the destination environment in the source database for accuracy and migration, leading to fast and enhanced performance. Bear in mind that the requirements of the source database must align or match with target database service-level agreements (SLAs), including maintenance, backup, and recovery.  

Expansion or Scalability Strategies 

Cloud technologies offer many benefits, including scalability support. It means the cloud can accommodate numerous business requirements. However, it is crucial to evaluate the efficiency and cost of the cloud’s scalability support. 

For instance, if you tend to use Oracle DB, it won’t support unrestricted scalability. On the other hand, PostgreSQL provides full scalability support because it is an open-source database. Therefore, it is crucial to define your scalability and expansion plans before migrating your database to the cloud. 

Security and Control 

Security and control are other crucial factors to consider when migrating from your source database to the target database. We recommend understanding the target security parameters to streamline the process. 

These include role-based access, host replacements, automated backup. Therefore, you have to focus on the target database’s security, control, and governance features. Otherwise, you will experience complications. 

Migration Cost 

It is one of the most critical factors when migrating your database to the cloud. You must conduct preliminary studies on “rent” and “purchase” models to analyze the metrics of cost of ownership in the source database and target database environment. 

Likewise, we recommend performing thorough research to understand whether the target or destination database aligns with your business goals. Makes sure you predict the return on investment (ROI) after migrating your database. 

For instance, if your business goal is to achieve efficient, accurate, and cost-effective performance after database migration, you will have to measure key performance indicators (KPIs) like records per minute processing time and the response time. 

Final Words 

Migrating your source database to a cloud platform offers many benefits, such as scalability, decreased administrative tasks, improved security, flexibility, uptime, and affordable costs. However, you have to consider the abovementioned factors before starting the migration process to avoid complications and save time and money.
