You need to do a backup/image to get a valid bootable system disk on
your target system; you cannot just copy over some specific directories.

That means you need to reduce the number of files on the source
system before creating the saveset.

Ideas to try before creating your saveset (completely untested, use
at your own risk, etc):

See if you can remove the sys$help and sys$examples contents, after
making multiple verified backups of them if you need to restore them.

Do a source_disk:[*...]*.*;-1 to check for multiple versions of files.

Did that version of VMS have any uninstall capabilities ?
If so, try removing any installed layered products with an uninstaller
and then install them again.

Try a source_disk:[*...]*.*/select=siz=min=1000 and see if you can
get rid of any of the files that show up.

How big are the swap and paging files on the source disk ?
They should be marked as nobackup, but they will be recreated on
the restore and hence take up space on the target disk.

Can you reduce the size of them on the source disk by using autogen ?
