After all, zypper live upgrade has been possible for a long time, but not officially suported. However, bugzillas on it were accepted. I wrote some! Couldn't the same be the case for the 32->64 process? It will become more interesting in the future.

If you or someone else is giving it a try can summarize on the Wiki, that would be nice.
