script or software for batch updating of files to version 10

[Bjørn Smalbro]

I have a client who wishes to update some thousand framemaker files and 
framemaker book files from version 7 to 10. Would anybody know a method 
for batch conversion? I suppose it can be done using Extend Script, but 
is one also able to handle the error messages which are bound to come, 
like missing fonts or pictures? I am not too keen on Framescript even 
though I am certain it works allright.
