Hi,
I don't know what's current status of this feature request, so please excuse me if my remarks are already specified/coded/tested :)
JFTR, I think you should also pay attention to :
- allow your DB migration tool to work on any database supported by OpenNebula (sqlite, mysql, maybe postresql soon #332 :)
- work from command-line (hint: called automaticaly by Debian maintainer-script)
- allow upgrade from previous versions (see my previous request for #181 and #415)
Regards,

Hi Damien, thank you for your comments.
Looks like we are in the right path:
- allow your DB migration tool to work on any database supported by OpenNebula (sqlite, mysql, maybe postresql soon #332 :)
The command works with sqlite and mysql, reading the connection parameters from the current installation's oned.conf, or from command line options.
- work from command-line (hint: called automaticaly by Debian maintainer-script)
That's a must for us, the cli comes first :)
- allow upgrade from previous versions (see my previous request for #181 and #415)
It will update databases created by 2.x versions.
Cheers
