Recently, a friend installed a x32 version of OS 13.1 in a i7 8Gb laptop computer. Apparently, it have 8Gb disposable for the operating system (Kinfo says), but I don’t think so, obviosly. So my question is, could we update from x32 to x64 as when we update from a older version to a newer, using “Update” option from install DVD?

Should be possible, yes. But I never tried it myself.
It should even work if you “upgrade” to the same version.
But you have to download the 64bit installation DVD of course.
A word of warning: You should not even try to switch architectures with the online upgrade method! (i.e. YaST or “zypper dup”)
This won’t work!
I tried this once, and it took me hours to clean up the mess…
Your explanation is crystal clear. My fault. I didn’t even wonder about how PAE worked and what was for.
Cause I installed to that laptop applications that was not in OpenSUSE repos (Chrome, Teamviewer and others) that should be downloaded and installed again on x86-64 versions, I’ll wait to OpenSUSE next release, and I will do an upgrade (“Update” option) from the DVD 13.2 x86-64 and then reinstall those applications. Knowing the fact that whole 8Gb of RAM are accesible, is not urgent to change software architecture.
Thank you a lot for your quick and understable explanation
