General procedures

Download and unpack the new MoinMoin archive

Download the MoinMoin code that you are interested in updating to. If you are not a developer, this is usually the latest released version from the project homepage.

Reading the docs

Please read the files docs/CHANGES and docs/README.migration contained in the moin distribution archive for details on what changed and how to upgrade.

The docs might contain import installation, compatibility and upgrade hints we won't repeat here.


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: X-(

As you want to make a complete backup (not even losing a single edit), you want to stop your wiki server process now.

This is what you should backup (the real paths depend on your installation):

Code update

First remove the old MoinMoin code (including any *.pyc and *.pyo files).

If you are installing from the original distribution archive, run "python install" as root to install the new version.

If you are using some Linux (or other) distributor's package, please read their docs.

Please also upgrade your moin.cgi (or moin.wsgi or other) server adaptor file. You likely have to edit it to fix some pathes and you also need to set some specific user/group/mode on that file (just look at the old one before replacing it).

Configuration update

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 and also changes that must break compatibility).

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

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).

Static stuff update

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. This defaults to /moin_staticVVV (VVV is 170 for moin release 1.7.0) and the default will change on every release (moin 1.7.1 will use /moin_static171 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.

Wiki pages update

System and Help pages

System and help pages are separately stored in the underlay directory. Just use the fresh underlay directory we provide in the distribution archive (move the old one to your backup directory).

If you previously modified some system page in your wiki (see EditedSystemPages on your wiki), you might want to Delete them to use moinmoin's updated version (warning: you can't un-delete that page later).

InterWiki data

Copy intermap.txt from the distribution archive into your wiki data

Your valuable own pages

See CHANGES and README.migration for maybe necessary steps to convert your data_dir to what we expect.

Clean your cache

Finally, delete cached data by running moin ... maint cleancache. This is necessary for things like the updated InterWiki data to trickle down into the pages that use it.
