Some quick notes on manually moving LibreNMS to a new server. For more detailed instructions you can refer to the following post

Backing up LibreNMS files
LibreNMS stores all it’s files in /opt/librenms
Quick and easy way to back up the LibreNMS files is to use tar.
tar zcvf librenms_backup.tgz /opt/librenms
I believe you can copy the whole /var/lib/mysql directory. Should be able to use the above command. If not you can do a mysqldump and then import it on the new system.
