upgrade from 32 to 64

Is there any easy way to upgrade a 11.0 install from 32-bit to 64-bit? My machine is capable of supporting the
cpu from what I have seen, and now I have an application that will really benefit from 64-bit. Is there some way I can do an inline upgrade via yast or something else, or even by upgrading over a 32-bit install with the 64-bit DVD? I am just hoping to not have to re-install everything on the machine…

Here is my /proc/cpuinfo output…

There is no easy answer to this I’m afraid.

The real benefits of _64 are seen if you have more than 4GB RAM, though a lower spec will still see advantage with processes like video encoding.

Perhaps with 11.1 just around the corner you would like to wait and do your upgrade then. Well it will mean re-install, but keeping /home as is will be fine.

You should be aware that there are issues with Flash and Java in _64. Though I use _64 without trouble, well Flash no problem, some Java issues but mostly ok.

There is no way to upgrade from 32 to 64 bit, you have to backup-reinstall-restore.

Sorry :\

Thanks, I was worried about that. I might just wait until 11.1 comes out then and rebuild. The main reason I need 64 is that I am running this small atom pc as file/media server and I am running ZFS/Fuse on it. there are several places where there are 64-bit ops low in that code and you pay a pretty big penalty running it in 32. Now we just need to figure out the legal stuff and get ZFS installed as a kernel level filesystem so I can get rid of fuse…
