Migrating from Earlier Releases

The QNX Momentics Tool Suite lets you install and work with multiple versions of Neutrino (from 6.2.1 and later). Whether you're using the command line or the IDE, you can choose which version of the OS to build programs for.

Note: Only versions of Momentics with different medial version numbers can coexist. For example, 6.3.2 can coexist with 6.2.1, but not with 6.3.0. However, 6.4.0 can coexist with 6.4.1 and 6.5.0. Coexistence with 6.2.1 is supported only on Windows hosts.

When you install QNX Momentics, you get a set of configuration files that indicate where you've installed the software. The QNX_CONFIGURATION environment variable stores the location of the configuration files for the installed versions of Neutrino; on a self-hosted Neutrino machine, the default is /etc/qnx.

Upgrading from 6.3.2 to 6.4.1 of the IDE involves two basic steps:

  1. Step 1 — converting your development workspace to be compliant with the latest version of the IDE framework. The IDE performs this process automatically at startup when it detects an older workspace version.
    Note: You can redirect the IDE to point at different workspaces by launching it with this command:

    qde -data path_to_workspace

  2. Optional Step 2 — converting your individual managed make projects. For more information, see Creating a make project.
    Note: Upgrading from earlier versions to 6.3.2 requires that you upgrade your projects to IDE 4.0.1, and then follow the two step migration process (above) to upgrade to IDE 4.6. For additional information about migrating, see Migrating from 6.3.2 (IDE 4.0.1) to 6.5.0 (IDE 4.7).
