[GeoNode-users] migration suggestions

Fri Oct 25 11:19:39 PDT 2019

Hi Alessio and Eugenio

I could recently update a GeoNode instance from 2.4 to master (2.10.1)
with not too much effort. Here are few notes I created at the time:

https://gist.github.com/capooti/32071c67fb2b40b7715256d287000155

Try this method on a dev instance before applying it on production.
Obviously, backup everything before doing it ;)

ciao
Paolo

So can I dump and restore both databases? or the db structure is changed, so that I need a special procedure?

>> What about the porting of the look and feel of the sites I have? just copy the codes?
