Operating systems considerations

There might be cases where you upgrade not just to a newer version of WebSphere Portal but also to a different operating system version. In that case, there might be a different set of system requirements and considerations to keep in mind.

Migrating between platforms (for example, migrating from Windows to Linux) is not supported.

Use the following list as a starting point.

• Review the supported migration paths.

• Review the system requirements for the new environment to make sure we are migrating to a fully supported environment.

• Ensure that you applied all necessary fixes in preparation for migration.

• Get a complete understanding of the differences between the source and target environments. The following questions will help you get started.

  • Overall system administration. Are there any monitoring or administering tools in use today that might not work on the new environment?

  • Operating system security. Is there any security polices in effect that would require being ported to the new environment?

  • Will WebSphere Portal security implementation be any different?

  • File system. Will the files be placed in a different directory structure? Will those files require special permissions to run?
