There is no safe way to do it, but it IS in fact possible. I have done it twice. It is a lot of work, and I recommend against it. However, where is the fun in life if you do not do something impossible once in a while? First of all you need a 64-bit kernel on there (not so difficult; you can just do rpm -i --ignorearch ...) Then you need to create a repository file containing the relevant 64-bit repositories in /etc/yum.repos.d/. It is a bit difficult getting started because yum will complain about duplicate files when you install some x86_64 packages over i386 packages. You can get around that by letting yum fetch the files and rpm --replacefiles. There is a risk of overwriting something vitally important and rendering the i386 part of your system useless before you have a viable x86_64 system. Have a rescue disk handy. Other challenges can be that you cannot necessarily trust the RPM database to survive the architecture change. You may have to manually remove /var/lib/rpm/__* and do a rebuilddb. Or reinstall from backup if that fails. You will also hit some cases where yum gives up in ways that it asks you to report to the maintainers. I have not actually reported those to the maintainers because I imagine that this is a highly unsupported use of yum. You can get around the problems with rpm --replacefiles and similar tricks. Again, do not do this if you are not prepared to lose all your data. /Benny -- devel mailing list devel@xxxxxxxxxxxxxxxxxxxxxxx https://admin.fedoraproject.org/mailman/listinfo/devel
