[GeoNode-devel] migrating data 2.6.3 -> 2.8

[Alessio Fabiani]

It is not easy to understand where the problem could be.

I would suggest to review the steps by carefully reading this page

http://docs.geonode.org/en/master/tutorials/admin/backup_restore/index.html

And also considering a manual migration of data by following those
guidelines

http://docs.geonode.org/en/master/tutorials/install_and_admin/geonode_update/26_to_27/index.html#update-from-geonode-2-6-3-to-geonode-2-7
