Upgrade From 32bit to 64bit

B

I'm running 8.1 Release Generic i386 - seems one of my applications may not be handling mail files larger than 2GB's.

I think I may already know the answer to this question, but thought I'd give it a shot.

Is there an easy solution to my being able to upgrade my 32bit box to a 64bit box? Or am I in for one of those long-weekenders?

The "new" box hardware-spec-wise is more than sufficient.

Thanks ahead of time for your input.
 
I think off_t is a 64-bit integer on 32-bit platforms, therefore I don't see why large files would cause trouble to a 32-bit FreeBSD system.

That said, moving to 64-bit FreeBSD _should_ be easy (backup, overwrite all userspace, recompile all ports), but will not necessarily solve your problem.
 
Back up, extract a 64-bit base.txz over /, restore config files that have been overwritten. Actually, I did it by copying 64-bit binaries from another system. Should have kept notes, it does come up fairly often. From memory, copy all the standard command directories, all the library directories, and /boot. Once it boots, install source, adjust kernel config, and do a full buildworld/kernel/installworld to make sure nothing was missed. Then rebuild all ports.
