Hi, 

AFAIK, preparedb will upgrade the DB to 5.5 and do some checks. No matter as 
you already use 5.5.

I would backup the database before halting the server and doing the preparedb.

You need to create the device class for the extractdb before halting the 
server. You cannot just add it to the devconfig file.

Regards, 
Erwann
