Backup restore command with multiple file extents

Hi all,

I want to restore my on-line vantage backup which was created with the
command "probkup online" in a test DB folder. I have several database file
extents .D1, D2, D3 etc in this backup. In the past I used the command
"prorest" to restore the backup. But since we have added the new database
file extents, this command no longer works anymore. Can anyone provide me
with the restore instructions for this type of on-line backup which includes
multiple database extents? Our database version is vantage 5.0.
