Only 64-bit systems are supported in Red Hat Enterprise Linux 7. You can use the output from the Preupgrade Assistant
to reach a configuration and package set suitable for migrating to a 64-bit Red Hat Enterprise Linux 7 system.
All the necessary information for migrating the system to a 64-bit version is available in the /root/preupgrade/kickstart/ directory.

If you have installed your own packages or packages from other vendors and you need them, check the support of 64-bit architectures or look for alternatives that you will be able to use on the new system.

Cross architecture migration is a new feature which we are still testing. Any feedback is gratefully welcomed and helps with future development.
