Hi, this method you speak of here.

Would it be possible to perform these tasks in multiuser mode, i.e. via
ssh ?  As I have no console to this server.

If the other drive will be big enough and if it will be running on
a machine with the same major version of the OS, use dump(8)/restore(8).

USe fdisk(8)/disklabel(8)/newfs(8) to put the appropriate file systems
on 
the new disk then dump the old one and restore to the new one. 
Something like:  (Assuming the old file system is mounted as /oldfs and 
the new is mounted as /dupfs)

  cd /dupfs
  dump 0vf - /oldfs | restore rf -

repeat for however many file systems you need to save and have room for.

Of course, if it won't read the old disk, then the problem is more
difficult.
