I am about to install a new motherboard to recover a hardware failure on an OpenBSD machine. The old MB had an Intel based CPU, however the replacement will support AMD64.
The old install was 4.0; obviously I wish to move to 4.1 at this time as well. I therefore want to migrate as much of the old setup as possible to the new kernel, and I am looking for advice on pitfalls in the two following strategies (and therefore which one seems the most direct): 1) install the amd64 system onto the root disk as a new "install", (ie; from CD), moving over important config from a preserved copy of the current /etc and /var after the first boot. 2) move to amd64 by performing an "upgrade" _on top of_ the existing i386 system, performing the usual upgrade path "final steps" to get things going. 3) "upgrade" 4.0 i386 -> 4.1 i368, and then "upgrade" 4.1 i386 -> 4.1 amd64 There are existing binaries on this system I would like to keep running (in 32-bit mode) if possible, but I want to avoid having a pot-pourri of libs of various ages and compatibilities. Can someone provide insight into whether the amd64 upgrade will provide 32-bit comptible copies of all libs in the 4.0 installation? Any advice appreciated . . . Andrew.
