Recreate nss trustees on other volume

Hi all,

I would like to move older files that my users had on the main nss volume on other volume.
For this reason I have prepared a new nss volume with the same directory structure,
and I would like that all directories on volume B (volume A is the main NSS volume)
had the same trustees database. Is than easy like copy .trustee_database.xml
and call ncpcon for resync trustees ?

thank you so much!
