[support] Merge sites/import & export?

[Adam Knight]

I have a rather ... odd situation.

I have two Drupal sites whose content must be merged.  That is, all  
the nodes and comments of site #2 must be somehow exported and then  
imported into site #1.  If the import-export module worked, I'd use  
that, but I'm on 4.7 on both sites.

Thoughts?  A simple MySQL dump will not do it because the ID numbers  
will conflict.
