I can do some consulting if you want :p
Which mail are you referring to?
and what do you mean by “crazy”? Performance-wise or did you have some bugs due to your inconsistent database?

I cannot.  
The reason why I need to do it is because the current database is  
already in a state which is driving nova-network crazy.  

I have sent an email a few days ago about the problem we are having  
with our installation. After some more checking, it seems that the
problem is caused by the *data* currently stored in the database; we  
tried with an empty one and everything was working smoothly: instances  
are started within one minute and deleted as needed, while going back  
to the original database brings back the issue.  

So, we guess it's something on the database, but we don't have either  
the time nor the competence nor the need to further debug the issue,  
since we are planning to move Havana soon and we have to keep the  
cloud up&running ASAP.  

Therefore we decided to clean up the database and remove more or less  
everything, but as I said, we would like to keep the information  
mentioned before.
