I'll say yes. I do believe I have upgraded after booting from an install
CD some time ago. At least installed a newer version over an existing
version. I think the hassle was matching the mount points to the right
slices, but this may be easier these days.

You may find it easier to manually install the tarballs from the CD -
you can find them on the disk in usr/freebsd-dist and install them with
cd /mnt/usr/freebsd-dist
tar -xf -C / base.txz
tar -xf -C / kernel.tbz
tar -xf -C / lib32.txz
You may also want to install some of the others -
doc.txz games.txz ports.txz src.txz

You can also download these installation tarballs without the entire iso
image if you want to save bandwidth.

Adjust the following link if you want i386 and for each tarball that
you want to download. Then use the tar commands above.
fetch
ftp://ftp.freebsd.org/pub/FreeBSD/releases/amd64/amd64/9.2-RELEASE/base.txz
