When the operating system, server, or database version goes to its end of life from providers, then it can trigger the cloud migration project, for example, upgrading the operating system of your web server from Microsoft Windows 2003 to Microsoft Windows 2008/2012/2016 or upgrading your Oracle database engine, and so on. Replatform involves upgrading the platform as a part of the cloud migration project. You can decide to update your operating system or application to a newer release as part of the migration.

When using the replatform migration strategy, you may need to reinstall your application on the target environment, which triggers application changes. This requires thorough testing on your application after replatform to ensure and validate its post-migration operational efficiency.

The following common reasons warrant the use of the replatform technique:

• Changing the operating system from 32-bit to 64-bit OS
• Changing the database engine
• Updating the latest release of the application
• Upgrading an operating system from Windows 2008 to Windows 2012 or 2016
• Upgrading the Oracle database engine from Oracle 8 to Oracle 11
• To get the benefits of managed services that are available from cloud vendors such as managed storage, databases, application deployment, and monitoring tools

Replatform helps you advance your application's underlying platform while migrating to the cloud. You can simply relocate your application to the cloud if it was deployed in containers or VMware. Now, let's learn more about the Relocate strategy.
