Hi Jeff,

The short answer is no.

The slightly longer answer is that the new style of packages are much 
more complex than the old ones because they each contain an actual 
sqlite database. So you could convert from the new style package "down" 
into one of the older style packages by querying the database and saving 
the results as simple environments. But you cannot easily go in the 
other direction.

We already support making new chip packages via SQLForge in the 
AnnotationDbi package for most major model organisms. What did you need 
this for?
