Learn code migration with online courses and programs

Upgrade to a new environment to optimize your application’s performance. Learn how to perform a code migration with edX.

What is code migration?

Code migration is the process of transferring code from one environment to another. There are three types of code migration, including:

  • Moving from one version of a language to another version

  • Moving from the current language to the target language

  • Moving from one operating system to another

A code migration can improve the performance of your application, as modern programming languages often have better efficiency than legacy languages. Newer languages may also provide better reporting, analytics, and enhanced integration capabilities.

Explore jobs that use code migration

The ability to perform a code migration might come in handy to a variety of different tech and programming roles. Some examples include:

  • Software developer: Developers build, test, and update software. Code migration can be used as part of a plan to update an application while updating to a new version or adding new features. Developers may handle the technical aspects of a code migration, and may work with other migration experts to develop and execute a migration plan. Developers may also build custom code migration apps to migrate custom code from one application to another.3
  • Database administrator: These administrators manage and maintain the database environment within an organization. They create backup plans during code migration to prevent substantial data losses or other issues. In some cases, database administrators may work on more challenging tasks in migration projects. Furthermore, they may support developers working on various code migration projects, such as Informatica code migration to migrate code between Informatica tools.4
  • Cloud engineer: These engineers work on the management of the cloud infrastructure. Code migration is relevant to cloud engineers as they play a crucial role in the code migration plan to transfer data to cloud platforms. For cloud engineers working with Magento, they use Magento code migration to upgrade to newer versions of Magento applications.5
  • Cybersecurity specialist: These specialists use various cybersecurity technologies to protect a company’s infrastructure and prevent hackers from exploiting vulnerabilities. They may use techniques like penetration testing on the migrated code to ensure that the code has not been left open to security risks by the migration process.6

A solid understanding of programming is helpful to any job in which code migration tools are used. Accelerated boot camps offered through edX enable learners to quickly upskill on topics ranging from cybersecurity to data analytics. Start building the programming skills you need for these roles in a coding boot camp.

    Frequently Asked Questions

    What are the steps in code migration?

    Code migration often starts with a planning phase to understand which code requires migration. An analysis then determines how compatible the code is with the new environment. The migration is then executed, with adaptation used to make any needed changes to ensure the code is fully compatible with the new environment.

    What are the models of code migration?

    There are different types of code migration models. One level of migration is the simplest and involves migrating from one version of a programming language to a newer version. Another type of code migration consists of migrating from one programming language to another. The most complex type of migration includes migrating from one operating system to another.

    What are the issues in code migration?

    One issue with code migration is information loss during migration. As code migration involves the transfer of vast amounts of code, it’s common for some information to get lost. The primary way to resolve this issue is to have backups. Another issue is compatibility with the new environment. It’s essential to thoroughly analyze the current and new environments to ensure the code is compatible. This analysis can help identify any necessary changes that require implementation in the new environment.

    How long does code migration take?

    The timescale of code migration depends on the amount of code involved and the scale of the migration. Upgrading to a newer programming language version is likely to be quicker than moving code from one operating system to another. Moreover, errors and compatibility issues can slow down the code migration process.

    What architecture best supports integration based on code migration?

    The two types of architecture include microservices and monolithic architecture. Monolithic architecture takes a broader approach, with any changes to the code potentially impacting the entire system but being potentially easier to deploy. Microservice architecture takes an alternative approach by breaking the application into smaller services, making it easier to manage the whole system. Since microservice architecture provides more flexibility and control, it offers better support for integration than does monolithic architecture because changes to individual units do not threaten the stability of the entire application.

    What are the steps to ensure code migration?

    A solid understanding of the code migration plan before executing it is vital. Moreover, having a backup of your code helps prevent losing it entirely if there are problems during the code migration process. After the migration is complete, carrying out tests can indicate if the code performs as expected in the new environment.
