Is it possible to bypass the need for installing a temporary Nuxeo 7.10 instance when migrating from Nuxeo 6.0 to 8.10? Maybe it is ok to apply the changes indicated in https://doc.nuxeo.com/nxdoc/upgrade-from-60-to-lts-2015/ and https://doc.nuxeo.com/nxdoc/upgrade-from-lts-2015-to-lts-2016/ before starting the new Nuxeo 8.10 instance on an existing Nuxeo 6.0 database. And if it is possible, is it even safe to do so? Thanks.
