Hi,
As far as i can see there are two possible ways to upgrade from
3.0a to 4.0:
1: Use the upgrade installation and go from 3.0a -> 3.2 -> 3.2C -> 4.0
2: Use a custom installation of 4.0 and restore the local changes of the
3.0a version.
A problem with method 1 is that i don't have enough free disk
space in the / partition to do an upgrade from 3.2c to 4.0. A workaround
for this would be to enlarge the / partition (/dev/rz0a) by decreasing the
swap partition (/dev/rz0b) and do a restore of the 3.2C root filesystem
on the, now larger, root partition. Together with the aprox. 2 hours for
each upgrade step this method would take 7 to 8 hours.
A problem with method 2 (custom installation of 4.0) is that i'm not
sure that restoring some local changes in e.g. ADVFS filesystem (/etc/fdmns)
layout and C2 security files (/tcb) will work.
For example restoring the /tcb directory structure together with the
/etc/passwd file should be enough to return my system to the previous
state. But DEC can/will not garantee that it will work and that my users can
still login with their old passwords.
Question.
I would very much like to hear any comments, experiences about which
of the two methods will be the best. In general any suggestions about
upgrading to 4.0 are welcome.
Thanks,
