If you need to import your existing external Trac instance to a Trac instance in CloudForge you will need to backup the environment first. This can be done using the trac-admin 'hotcopy' command. Please check the documentation to perform your trac backup at http://trac.edgewall.org/wiki/TracBackup.
Once you have your backup, you can zip and send it to us: You can either upload it on your CloudForge WebDAV Drive or send us via email to firstname.lastname@example.org whichever is easier for you. Once we get the backup we will import it on your Trac project.
