Has anybody done this, an upgrade from 32 to 64 bits? Does it work? Is it "supported"?
yes, this is supported.
Define "supported". We will WONTFIX all bug reports about it and it's not tested at all. I wouldn't call that "supported".
Ugh. This is very discouraging. Actually, your very answer poses one or two bugzilla reports; I'll explain.
(Note: I'm in no way attempting to use zypper upgrade. I'm booting from the retail DVD, the classical upgrade method, or "dead" upgrade)
1) I'm booting from the retail DVD, which says it supports both 32 and 64 bits versions. However, in a 64 bit machine I see no way to select a 32 bit install or upgrade.
2) The retail DVD, when asked to upgrade possible installs, does not automatically propose to upgrade the existing 32 bit installation (it only sees the 64 bit install). When manually pointed to the partition containing the 32 bit install, it does not propose to upgrade to 11.2-32 bit.
2.bis) Instead, when pointed to the partition containing the 32 bit 11.0 install, it actually proposes to upgrade to 11.2-64 bit. The message box says:
| The architecture of the system installed in the | | selected partition is different from the one of | | this product" [continue] [cancel] |
If I press "continue", it goes trough the upgrade motions; I did not go on, I cancelled in order to ask here first. Several people (some in private or in the other list) have said they did it sucesfully.
The issue is, if this is not supported at all, the install DVD should warn the user about this, and then give the option to continue in 32 bit mode, or explain how to boot the DVD in 32 bit mode to retry.
As it is, the retail DVD behaviour implies that upgrade to 64 bit is the only possible procedure.
I'd propose that the message be modified. I has to either say that it is not possible, or that it is not supported at all (and explain how to switch to a 32 bit upgrade). I would also like you (suse) decide to "mildly" support the procedure, in low priority mode, at least, and perhaps point to a wiki page with cautions, pitfalls, sugestions, alternatives, etc.
The thing is, people have done this upgrade sucesfully. It is a very interesting posibility, even if not for the inexperienced. I'm not requesting full support, that is not possible, but at least, some help.
Either that, or completely discourage the procedure in the message box. As it is, suse devs have designed the DVD to do or attempt this upgrade, that is clear. How far, that is not clear.
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.
