I guess, wget'ing the bsd.rd from ftp.openbsd.org mirror would be the
best installation media, but then upon reboot should I choose
'upgrade' and do 3.6 - 3.7, then repeat the procedure with 3.7 -
3.8, then cvsup and compile the -current from sources? Or should I
'install' 3.8, then cvsup -current, and compile?
The FAQ somewhere suggests of course, starting with a fresh install
is always best.
If I'll choose to install 3.8, then will I be able to leave my
partitioning scheme and contents of my custom partitions intact? Or
will I have to repartition the drive?
The install script does run fdisk and disklabel but there's no reason
you can't simply quit both immediately without making changes. All
installing consists of is untarring the various install sets,
writing some /etc/*.conf files with info from the user, using MAKEDEV
to make various device nodes (not that I really understand what that
means) and--oh--running newfs. I guess it would kill your partitions
then. Probably upgrading is your best bet then, and I'm pretty sure
you can go 3.6-3.8 immediately. Perhaps you could install by hand if
all else fails?
The FAQ says skipping releases is not supported. :-)

You have an entire partition for mozilla? I'm curious why (I'm
somewhat a newbie, I like enlightenment).
I am a mozilla contributor. :-) I used to build it in /home on
FreeBSD, which actually was /usr (/usr/home), and it all got too messy
(`find /usr -name somename` became too awkward etc). So I decided to
play it cool with OpenBSD, in case I'd like to hack mozilla again.

Upgrading 3.6 to 3.8, and compiling -current
Hello,
At a remote location, I have two boxes that are connected with each
other via a serial cable, and through a router to the internet.

and then compile -current (I want to play with the kernel alongside
sensors.h / lm(4)).

P.S. Is the upgrade really that simple and straightforward on OpenBSD
as it seems to be? :-)
P.P.S. BTW, as you can see I have some free disc space left... Is it
possible to install two versions of OpenBSD on separate slices of one
HDD and multiboot them? Or better and simpler just do the upgrade? :-)
Thanks,
Constantine.

Or will I have to repartition the drive? should be fine intact - you have plenty of space on /usr for the libs which are now larger since they have debugging information (and very useful it is too). if you were tighter on space (mainly in /usr), you would want to make sure softdep is off while you upgrade.

Of course it's possible to multiboot them, so long as they live on
separate MBR partitions. Then just use
$sudo fdisk -e wd0
flag n #n is 0 or 1, the partition you want to boot from
to switch between each.
But reallly... it's simpler to upgrade.
