What do you mean by “clean”? Contrail will ignore all information in the neutron db. Any incoming neutron api call will be translated to a contrail-api call. Contrail itself does not use the Mysql database but has its own (Cassandra) databases So any router/subnet/network/interface etc object that currently exists in the neutron/mysql database is ignored. That basically means any object that is using “stock-neutron” will break since it will need to be re-created on contrail. Cheers, Robert van Leeuwen
