Procedure generali
Scaricare e decomprimere l'archivio di MoinMoin
Scaricare il codice di MoinMoin della versione a cui si vuole aggiornare. Se non si è uno sviluppatore, la versione da scaricare è l'ultima versione stabile rilasciata.
Molto spesso è meglio (e più facile) installare l'ultimo rilascio dagli archivi piuttosto che usare la versione fornita dalla propria distribuzione Linux.
Leggere la documentazione
È molto utile leggere i file docs/CHANGES e docs/README.migration contenuti nell'archivio del programma per i dettagli su cosa è stato modificato e come eseguire l'aggiornamento.

Backup
Before you update an existing wiki, MAKE A BACKUP!
You have been warned, and it's not our fault when you end up like this: 
As you want to make a complete backup (not even losing a single edit), you want to stop your wiki server process now.
There are two directory trees which you should backup:
The one containing the MoinMoin code files (e.g. /usr/lib/python*.*/site-packages/MoinMoin)
- after you have a backup of this, you might want to delete the MoinMoin directory there to avoid having old code files there that are not overwritten by the new code, but maybe interfering with it)
The one containing your data (e.g. /usr/share/moin/wikiname/data - see data_dir in your moin_config.py).
The real paths depend on your installation.
You also need to backup:
- your moin.cgi file (or moin.fcg or other adaptor file you use)
- your wikiconfig.py or farmconfig.py or other wiki configuration files
- your web server configuration files
Aggiornamento codice
If you are installing from the original distribution archive, run "python setup.py install" as root to install the new version.
If you are using some Linux (or other) distributor's package, please read their docs.
If CHANGES tells you, you maybe also need to upgrade your moin.cgi (or moin.fcg or other adaptor) file. You maybe need to set some specific user/group/mode on that file (just look at the old one before replacing it).
Aggiornamento configurazione
After upgrading, your existing wiki should continue to work (the goal is to have sane defaults for any new config values, but then there can be bugs).
Check that this is indeed the case, and then take the time to check the CHANGES file in your distribution archive. Often, new features will be invisible unless you extend your configuration in wikiconfig.py (1.3+) or moin_config.py (<=1.2.x).
Check that you have the latest "intermap.txt" file; If you have your own entries, you can point "shared_intermap" at a file loaded before the file in your data directory, which takes precedence (i.e. have global entries in the shared one, private entries the data dir file).
Aggiornamento oggetti statici
On every update, you should copy the content of the "wiki/htdocs/" directory we provide to the directory visible to your web server, normally a new release has some new images, CSS and Javascript in it.
You also have to change your web server / directory setup to match the url_prefix_static setting of moin. Starting with moin 1.6, this defaults to /moin_staticVVV (VVV is 160 for moin release 1.6.0) and the default will change on every release (moin 1.6.1 will use /moin_static161 by default). This is done to be able to use a very long cache lifetime for the static stuff, so your wiki will be faster and cause less load and traffic.
Aggiornare pagine wiki
Pagine di sistema e di aiuto
Since moin 1.3, system and help pages are separated in the underlay directory. Just use the fresh underlay directory we provide in the distribution archive (and throw away the old one).
For pre-1.3 procedure, please see CHANGES file.
Le pagine più preziose
See CHANGES and README.migration for maybe necessary steps to convert your data_dir to what we expect.
Risoluzione problemi
A good idea is to do a request for "...?action=test" (which calls an internal diagnosis feature) after you installed a new release, which will spot some common errors. If one of the tests fails, don't panic, but see CHANGES if it is a known effect.
Depending on your installation, more tightly secured permissions are a good idea. Ideally, you assign all files in the data directory to the user the web server runs under, and then you use 700 or 770 - see also the config.umask setting.
