General procedures


/!\ 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-(

There are two directory trees which you should backup:

The pathes depend on your installation.


Download the MoinMoin code that you are interested in updating to.

As root, run "python install" to install the new version.

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). Check that this is indeed the case, and then take the time to check the CHANGES file in your distribution. Often, new features will be invisible unless your extend your configuration in "" (1.3:

This is especially true for:

Updating files


On every update, you should copy the content of the "share/moin/htdocs/img" directory to the image directory visible to your web server, normally a new release has some new images in it. If you use the default distutils setup scheme, this is no longer necessary (distutils updates the files for you, and your webserver gets the files from the installed images).

System pages

When upgrading to a new version, copy at least the help pages ("Help*") to your existing directory. Then check whether you miss any new system pages. In 1.3 these pages are kept separate in the underlay directory.


Check that you have the newest "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).


A good idea is to do a request for "moin.cgi?action=test" (which calls an internal diagnosis feature) after you installed a new release, which will spot some common errors.

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 755.

Upgrade information for specfic versions

The following sections provide information pertaining to specific versions of the software; if you jump several versions, read all the sections applying to your situation.

Version 1.0

Version 1.0 is the last to support Python 1.5.2, but some optional features (like statistics) already require Python 2.0.

Version 1.1

Be sure to read the above section on General procedures before you start upgrading.

Version 1.1 requires Python 2.0 or higher, we recommend to use Python 2.2 (version 2.2.2 if that is available on your host) or even better >= 2.3.2 (with 2.3.x, MoinMoin runs about 20-30% faster).

Upgrading your configuration

Enabling new features

Version 1.2

Version 1.2 requires Python 2.2.2 or higher, we recommend to use Python >=2.3.2 (with 2.3.x, MoinMoin runs about 20-30% faster).

Version 1.2.1, 1.2.2, 1.2.3

As 1.2.x is primarily a bug-fix release for 1.2, there is not much special if you run 1.2 and want to update to 1.2.x.

If you run a version previous to 1.2, please read above about upgrading to 1.2 first.

In any case, read the CHANGES file in the toplevel directory of your moin archive - all fixes are described there and also some few new features.

Be aware that except code fixes, there were also fixes in the data and htdocs directory - so please selectively copy them over to your running wiki installation.

Version 1.3

/!\ Upgrading to moin 1.3 will be non-trivial. It will definitely take you more than 5 minutes. /!\

This is because of many changes to configuration, data format, filenames and pathes.

In any case, make a backup or you risk destroying your wiki's content.

Please read the CHANGES file in the toplevel directory of your moin archive for details on what changed and how to upgrade.

Deprecation Note

This page is deprecated (at least the version specific stuff on it), for 1.4 it will be gone and we will use CHANGES file exclusively.
