Data Migration Process - Top Considerations and Key Phases

Drive Business Growth with Data Analytics

Data migration has become very important for businesses today. Data migration frequently involves consolidating data from many cloud and on-premises source systems into a single centralized repository to minimize data warehouses and establish organization-wide information access. One of the most common reasons for undertaking data migration is the requirement to move data from a legacy system onto a new system, most likely in the cloud.

Cloud technology has proven to be very helpful for businesses today as it helps them to quickly scale up and down in response to market demand. Data migration is a crucial part of an enterprise migration plan to the cloud or anywhere else. A data migration strategy is necessary for organizations moving to a cloud computing environment, such as a hybrid cloud, public cloud, private cloud, or multi-cloud, to ensure a secure, simplified, and affordable data conversion process.

Most Significant Considerations of a Data Migration Strategy

Regardless of the precise motivation for the relocation, businesses require a sound data migration strategy. Incorrect and redundant data are less of a risk after successful data migration. These risks can still arise even if the source data is reliable and any issues that already exist in the source data are exacerbated when transferred to the new system. The key considerations of a data migration strategy are:

Data quantity: There are numerous data migration tools available that can assist you to move data into the cloud. Your cloud vendor will provide a tool for you to transfer your data over if your data demands are reasonably small, such as a few hundred columns and rows in a single set of data without a tonne of sub-tables. The data is received precisely as it appeared in the source system.

However, if you want to transfer enormous volumes of data, such as moving an entire corporation to the cloud or even just one important system, you would require a more complex solution for it. The more data you are attempting to transport, the more challenging it will be. You will need visibility, control, and technology that can alter data as it flows to the cloud to guarantee the quality of your data.

Making the data fit for your purpose: When transferring data from an on-premises system (A) to a cloud-based system (B), you frequently need to alter, conform, or reshape the data so that it functions as system B requires. Many teams that are brand-new to the cloud technology and under time constraints duplicate what they did on-premises into the cloud. However, this prevents you from benefiting from cloud designs. To achieve that, you must ensure that the data is optimized for the new system where it will be used as part of your data migration.

Data migration duration: Depending on the volume of data and the technology you choose, data migration can take a long time. It is crucial to understand that, even though a migration tool with data pipelines that send data directly without any modification may move more quickly, the trade-off in diminished performance and other advantages of cloud architecture is not worthwhile.

Big Bang and Trickle Strategies: There are two types of data migration strategies. They are the Big Bang and Trickle migrations.

In the big bang data migration strategy, organizations complete the entire transfer quickly in one go. In this migration strategy, the live systems will experience a period of an outage when the data moves through the extract, load, transform (ETL) process and to the new location. However, there is a chance for very expensive failures, and the necessary downtime may have an adverse effect on customers. Since data nowadays needs to be continuous, a trickle data migration is considered to be the best data migration strategy. During a trickle data migration, a company completes the migration over a longer period in manageable phases.

Different Phases of the Data Migration Process

Most data migration projects comprise planning, migration, and post-migration. Ongoing data synchronization, which is also mentioned here, is a crucial fourth phase that is far too frequently disregarded. Each of these steps may recur several times before the new system can be recognized as fully validated and deployed, depending on the complexity of the particular project.

Data migration plan - Based on the specific business, project, and technological requirements and dependencies, the enterprise selects the data and applications that must be moved during the data migration planning stages. The company needs to assess the hardware and bandwidth needs for its data migration operation and develop realistic migration scenarios, along with accompanying tests, mapping, automation scripts, and procedures.

Additionally, it must choose and create the migration infrastructure and implement change management practices. The organization also decides what frameworks for data preparation and transformations it needs to improve data quality, avoid the possibility of duplicate data, and guarantee that data is optimized and conformed for the new system.

Data migration process: During this stage, the business must modify the intended migration method and confirm the particular hardware and software requirements. This could go as far as pre-validation testing to ensure that the settings and requirements work as intended. You may either utilize a contemporary data integration solution that enables you to skip that time-consuming step by automating multi-table updates, or you can take the effort to comprehend what your source schema looks like and then duplicate it precisely in a new system. Assuming everything is in order, the data migration process begins, including data loading into the new system and data extraction from the old system.

Post-data-migration data verification - After the migration, data is verified to make sure it is accurate, and complete, and supports the various operations in the new system. To identify any discrepancies and prepare for data loss, it might be required to operate the new system and the existing system simultaneously. Typically, data migration reporting takes place, and any legacy systems are decommissioned by the company.

Continuous data synchronization - After data has been moved, businesses must continue to synchronize it between various systems, databases, applications, and devices. As a result, correct and compliant data are delivered continuously. Real-time, consistently consistent data distribution is made possible through data synchronization.

Cross-Database migration - A special type of database migration

Cross-database migration from open-source databases like PostgreSQL and MYSQL to Azure has recently gained popularity in the IT sector and offers significant benefits.

Cross-database migration is a type of database migration that allows you to move and transport database schemas and data between database types. Companies can choose to switch from one database to another for several different reasons. A business can choose to use an open-source database like PostgreSQL or MYSQL on Azure to conserve resources. Similarly, a company might choose to undertake cross-database migration if it finds that a certain database satisfies its unique set of operational needs. To reduce issues throughout the data migration process, a good database conversion plan must be established.

Cross-database migration can be very beneficial to your business, and it is starting to gain popularity too. This is partly because using open-source software is totally free, which is one of its major advantages.
