Using ontape -r to start a cold full system restore!

Dear all,

I have a level-0 backup archive of IDS 7.31 and i want to restore it in
another host. Now i met some problems. Can i change the rootdbs
location to a new one?

For example: when i use onstat -d in the IDS instance host and it will
show:

/dev/vx/rdsk/datadg/lvrootdbs is the location of rootdbs.

But in the new host, i want restore the rootdbs to a new location,
maybe change it to /dev/rdsk/lvrootdbs. Can i do it use ontape tool?

OR someone knows use some other IDS tool to make a archive, and then
change the location of database space during the restoring process?

It is very appreciate of your point.
