The easier method is to use the V1.5x gbak utility to backup the V2.0
database through the V2.0 server. If you use the new V2 metadata
features - base collation and collation attributes - you'll lose the
data in them because V1.5 doesn't know to ask about that. But you'll
get a file that can be restored under V1.5.
