Hello managers,
My original question was ...

the

>/usr can take the size of the old /usr + the old /home ?
The general (and correct) opinion was that unless one had Advfs the
new space cannot be used by the fs. So we did a dump of the current fs onto
the newly installed and partitioned disk ... and then repartitioned the
old disk and restored.
One other point that I thought ... I should mention was that when one is
migrating to higher size disk - if the new disk is to be made bootable all
one needs to do is to dump the root partition of your old disk onto the new
one along with the /usr of the old disk and and edit the fstab entries in the
new disk and lo, one can then boot from the new disk !!
I initially had some doubts about the binaries ... in /mdec being different
for different size disks (which is fact) but upward migration seems to
pose no problem whatever !!
Hope that makes things clear.
Thanks once again to all who responded.
