[Joe Topjian]

Yep, absolutely:

https://github.com/cybera/novanet2neutron

The changes are all rolled into one commit:

https://github.com/cybera/novanet2neutron/commit/31a6ef0eaebb84b94f4cc97d4f0acfffb4eed251

Note that we hard-coded the network and subnet names in there, so if you
end up using this, you'll want to change that.

Thanks,
Joe

Hi Joe,
congrats.

Can you also make available your scripts changes for IPv6?
The more the better for any site that is still working in the migration,
like us :)

thanks,
Belmiro
