[Sunhelp] Filesystem

[Giorgio Guagnini]

Hi at all,
My name is Giorgio Guagnini from italy,
i'm a novice in solaris.
I have a sparcstation 5 85 modified by me at 96 mhz  with solaris 7
installed in 1 gb hard disk but i have low free space for data and
programs.
I want copy my filesystem in  hard disk of 4 gb.
I have initialized it with FORMAT and after ,in single user,copied the
filesystem with CP  recursive but not functioning.
Is there an command as ufsdump or other that permit me to transfert
filesystem directly between two hard disk of different capacity?
Thank at all !
