My original question was:
********************************
I'm trying to upgrade Alpha Station 255 from DU 3.2D-1 to DU 4.0D. I
arranged installation media also for DU 4.0 and DU 4.0A. I successfully
upgraded firmware. When trying to upgrade to 4.0, installation procedure
responsed with the message regarding not enough space on the root
partition. I tryed to remove all unnecessary files, but the message
remains.
The size of root partition is 64 Mb and it is probably not enough for
upgrade to 4.0D.
I do not have much experiences with administrating DU, but with help of
manuals I found out, that there is probably one unused partition of 800
Mb on the hard disk which can be used as root partition.
Please, give me some advice, how to transfer root partition to this
unused part of the disk.
********************************
Thanks to all replayers!
All replayers recommended me not to transfer the root partition, but to
enlarge it. I found the step-by-step advice to do this in the SUMMARY:

Here are the individual replays:

Don't bother trying to move it. Moving the root away from
the first partition of the disk is probably little tested
and may not work. What you need to is:
a. Get a 2nd disk, partition it for the root to have more
space and migrate the existing root to that.
b. Backup the existing root, make the partition larger and
restore.
Since B will cut into the primary page/swap space, you'll
want to move each file system, to grow the others. Fortunately
you have that H space available for growth.
FIrst figure out how you want to repartition. V4 is using
128 MB for the root file system, so you at least want to
grow the A partition by 64 MB. That means changing the
offset of B. You may also want to grow it while you're
there. This in turn affects there G starts, which means
using H.
So, shutdown to single user, and get a backup of all the
file systems on the affected disk. Use vdump. Remove
the file set and domain for /usr and repartition G and H
so that you have room to move B. Use the disklabel command
with the -e option. Once G and H are repartitioned, recreate
the domain and usr fileset and restore. To do the root
you'll need to boot from the CDROM.
The procedure here is basically the same, only your using the
standalone system.

Your best course of action is to backup all files from the old OS 3.2
(perhaps DAT, CD-R or another disk). Ensure that you have upgraded the
firmware (which you mentioned that you have) and then install DU V4.0D
from scratch so you can resize your / (root) to 128Mb and /usr to 700Mb
(approx). To boot from CD following steps:
(DU 3.2)
# /sbin/shutdown -h now
(it will then drop down to the SRM console)
>>> show dev
(will inform you of your devices)
>>> boot dka400
(if you CD is device dka400)
This will then boot from CD and then you'll be presented with various
option such as; system information, software selection and most
importantly (for you) partition disk.
Good luck and I hope this helps.
Regards,
Rich

Since your root partition a is AdvFS, the easiest way is to use
`mkfdmn' to make the partition h an AdvFS doamin and then put a and
h together.
Long way is to backup the disk, relabel it by pushing b and g
downwards thus expanding a.
Goodluck,
