What Are the Different Types of Database Migration?

 

If you are working in the digital industry, then you probably have heard of database migration. It pertains to the process of moving data between two or more types of storage. The transfer could take place between different computer systems or formats. In other words, it is the process of moving data from one platform to another. 

There are different reasons why data is moved from one platform to another such as saving money, organization, and efficiency. The process involves different phases and iterations that must be assessed based on business needs. Here is a detailed explanation of different types of data migration and the reasons behind each type.

Reasons to Why Data Migration is Done

  • Cost-efficiency 

Financial savings are one of the top reasons why database migration is done. Usually, moving from an on-premise database to a cloud database could cut infrastructure and manpower expenses.

 

  • Modernization 

The migration of databases is primarily done to move from an outdated system/legacy system to a modern system – one that meets the needs of modern data. The world is constantly evolving and so is technology. Hence, there is a necessity for a new storage method. 

 

  • One source of truth 

Data migration is also done in order to have all data available in one accessible source for all divisions of the organization. It usually takes place after an acquisition, specifically if the systems need to be combined. It also takes place if the different systems are siloed throughout the organization.

What is database migration in SQL Server?

Migrating data in SQL is done for different reasons. The process, data is being moved to the different instances of SQL and restoring databases from a backup, to name a few. There are two ways of moving data in the SQL server – manual and command line. The method of choice depends on the type of task you need to accomplish. The manual method is ideal if you are going to move a few databases. However, if you are going to move mass databases, the best method is a quick and secure automated process. The command line may need a lot of preparation, but it is a preferable approach.  

 

What are the different types of data migration?

The migration of data can be done in many different ways. There are four primary types of data migration and these are the following:

 

  1. Storage migration – As the name implies, the physical blocks of data are moved from one type of hardware to another.

 

  1. Data migration – The entire database is moved from one vendor to another or the current software being used for databases is upgraded.

 

  1. Application migration – The need for transformation is a must if the application vendor has to be changed. It is a must considering that every application operates on a particular data model. 

 

  1. Business process migration – It pertains to the business practices of a company, specifically, business management tools that need to be replaced or upgraded. It usually happens in the event of a merger or acquisition. The data transfer is needed for anything from one business, database, or application to another. 

 

What is database migration in MySQL?

There is a need to move MySQL databases for varying reasons. It could be the need to transfer data to a testing server or to move the entire database to a new production server. With migrating data in MySQL, a robust database migration can be achieved. The migration process is easy too as it would only require a few simple steps. However, the entire process duration may take some time depending on the bulk of data that needs to be migrated. Luckily, Accelario’s MySQL Data Migration system supports minimal downtime during the process.

 

There are also instances when you need to migrate data between two MySQL servers such as when separating database for doing reports, cloning a database for testing, and when completely migrating databases to a new server. Generally, you would need to back up the data on the first server. After securing the data, you will proceed with transferring the data remotely to the new destination server and restore the backup on the new MySQL.

What is Database Migration

Think about data migration as birds migration – the necessity for resources. Birds migrate from an area with limited resources to areas abundant with food and ideal nesting conditions. How is that relevant to data? When data migration relates to enterprise applications, companies move data from one platform to another for resources that are critical for business operations. 

Out of the many reasons for database migration, the most common, financial reason, is to save money with a cloud-based database. The need for new technical features also strengthens

operations necessary for competitive advantage. Simply, outdated data supporting platforms may not work with modern applications and marketing automation tools. We will go over the importance, processes, challenges, and solutions of data migration. 

Why is database migration important?

On-premise vs cloud-based database  

Think about your customers’ behavior – web browsing for the best deal, comparing reviews, or completing an online form. All of these behavior patterns and research methods are supported by cloud-based migration. The most-known, multinational tech companies such as Amazon, Google and Apple all involve cloud data-based operations. Data operating on the cloud meets consumers’ needs and habits with reliability, availability and security. 

Cost optimization 

Moving from on-premises to a cloud database is cost-effective. Companies move to save money on infrastructure and required skills (manpower) for on-premises database management. Many businesses understand the cost-savings of cloud environments as the main reasons for cloud-based migrations. 

Software development

Remember the modern consumer habits we discussed earlier?  In this era of big data, new data storage techniques are key to success. For example, companies migrate from a Microsoft SQL service to cloud platforms as part of an adaptation to modern data needs. New storage techniques on the cloud provide a solid ground along with operational flexibility. In addition, with cloud migration, companies can quickly move new and existing applications straight to the customers’ screens. 

The core of operations

Moving data to a cloud platform provides access to all divisions of the company. Especially when multiple channels are combined in the business model, a one-stop data source is highly efficient for multi-channel operations. With strategic planning, data is delivered applicably to the different teams: IT, marketing, or management. Optimized data flow from a one-sourced data channel fuels the operations of each department while providing insights for the management. 

Scale-up

For multinational organizations and small startups, on-cloud data provides an opportunity for growth. Customers are used to quick accessibility. When a company has access to behavior analysis, all divisions can drive growth.  Also in many countries, data protection is a nationally regulated procedure that should comply with the local regulations. While using third-party data migration support, companies don’t need to worry about regulations that are covered by the cloud platform.

What are the different types of data migration?

There are four main data migration types: storage, data, application and business processes. 

Storage migration

Exactly as storage sounds – it’s the outdated, physical hardware that stores the data. To enhance flexibility and save on operational costs, companies move data from a physical location to modern cloud systems.

Database migration 

Based on business needs, databases can be moved completely from one vendor to another. This also takes place with software updates or from one cloud platform to another. 

Application Migration

The migration of applications to modern environments is performed from an on-premise environment to an on-cloud application or from one cloud platform to another. 

Business migration

Business processes migration usually takes place during management changes and acquisitions. During such processes, there’s a need for new tools and movement of data to be accessible for new divisions. 

How does application data migration work? 

Clean data migration phases include planning, file allocation, migration, and testing. 

Data profiling 

The initial stage is data profiling and resource assessment. During the process of data profiling companies allocate data location and schema. After finding data in the existing location (database or files,) data should be organized in informative and optimized patterns. In addition, planning takes into consideration the cost and requirements that will be involved. Integrating data into the new platform may involve risks, which are solved with secure transformation methods.

Files migration

Data migration applies to all of your environments. When migrating small or large batches of files, the process should be simple with minimal cost and downtime that can affect business operations. 

Schema conversion  

Database schema refers to an organization of data in an organization – a blueprint of database hierarchy and relationship between different data groups. While moving data from one source to another one, you need to ensure there is a compatibility between the new platform to support the old blueprint.

Data migration operational suite 

After you have ensured that data schema is supported, you can start the actual migration. Without expertise, this process may be complicated. Luckily data migration and operation can take place with fast, self-service applications. There’s an opportunity to quickly migrate and deliver data to new or refreshed databases with minimal downtime and without specialized engineering skills. 

Testing 

Once your DevOps or someone from the QA team has moved the data, testing is necessary to ensure that no valuable information is missing. During the testing phase, you can setup modeling and backtesting data sets, while ensuring data privacy and protection. Testing data transformation can be a lengthy process. Especially because during the migration stage, data is masked and encrypted to avoid sensitive customers’ data breaches. A new automated tool gives a fresh perspective to data masking and testing with data refreshment and duplication.

3 Database Migration Challenges 

Most digital companies require information systems to support business processes. Secure data migration is a critical element when a company decides to improve operational flow with the new data platform. Moving data from one storage to an online destination without affecting operations sounds easy, but without proper technical support, this process can crush a company of any size. Proper planning is the answer to all data migration challenges.

Databases allocation

For many companies, multinational operations are common. Your company’s headquarters may be in the US, while your IT and customer support are in another state or country. Allocating the operational data storage map is the first (and key) step to successful data migration. At a larger scale when acquisitions take place, companies need to define data migration schema from various geographic areas. 

Data loss and corruption 

Fast data migration is crucial, but the speed must be supported with advanced security with features such as data masking and subsetting. Tested third-party data migration software is crucial for a corruption-free process without valuable data loss. 

Secure data protection 

It’s not a secret that there is an abundance of trolls that would love to get their hands on your data for a decent reward. When moving data from one source to another, it’s critical to secure the data. You can encrypt or mask all personal and financial information during data migration.

Our database zero downtime migration with AWS DMS

Database zero downtime migration with AWS Database Migration Service and Accelario

AWS BLOG

This is a guest post by Michael Litner, Co-founder and VP R&D of Accelario.

Accelario is database migration software that provides a fast and easy way to load an Oracle database to Amazon Web Services (AWS). At the end of the initial load, database synchronization starts immediately using AWS Database Migration Service (AWS DMS), and the result is a zero downtime migration of your database.

Businesses that require 24/7 operation face a significant issue when moving databases into the cloud: Up until now, few if any cost-effective options existed to minimize the resulting downtime. With its recent integration with AWS DMS, Accelario provides a ready-to-use, zero downtime, full database migration solution—meaning that the whole database is migrated, including users, procedures, views, etc. When the process is done, you can access your database and start using it with your application immediately.

Another significant issue affecting such businesses is ensuring that sensitive information is not exposed as part of the process, which is critical for complying with data protection policies and regulations. You can achieve encryption of data in transit by using Oracle’s built-in features (including network data encryption)—also supported in Amazon Relational Database Service (Amazon RDS).

In this post, I go over how to use this combined solution to migrate a database to either Amazon EC2 or Amazon RDS (also using data masking). I also show you how to easily refresh a database after it’s in the cloud.
