Detailed system requirements »

Installation

1. Download (see above)
2. Unzip the distribution ZIP file
3. After unzipping, double click on the file b2evolution/index.html for quick start instructions.

Regular upgrade

1. Download the version you want to upgrade to (see above)
2. Unzip the distribution ZIP file
3. After unzipping, double click on the file b2evolution/index.html for quick upgrade instructions.

The regular upgrade procedure works for upgrading from any version of b2evolution to any more recent version. b2evolution's installer/upgrader will automatically detect which older version you are upgrading from.

However, starting with version 1.8.2, any minor upgrade (3rd digit upgrade as in 1.8.1 to 1.8.2) will not require any database upgrade and you may be able to upgrade just by replacing a few files. See quick upgrade patches below.

For example: upgrading from 1.9.0 to 1.9.2 only requires to replace the application files (attention: make sure to properly update your /conf files!). No database upgrade necessary. This means you can also downgrade back to 1.9.1 or 1.9.0 as easily. You could not downgrade to 1.8.x without restoring a database backup, though.

Quick upgrade patches

No database upgrade is necessary if you only want to upgrade from a.b.x to a.b.y, for example, from 3.3.1 to 3.3.2. You can upgrade just by replacing a few files. Just make sure you properly update your /conf files.

Got diffs?

If you are an advanced linux user/admin/coder, you may want diff patches instead. You will find them at diffs.b2evolution.net .

Migration

If you want to migrate from b2/cafelog or Movable Type, just follow the instructions in the latest release.

If you want to migrate from Geeklog or Manywhere Miniblog, first import into b2evolution 0.9.2, then upgrade to the latest version.

If you want to migrate from any other blog tool, we recommend you try to export the contents to the Movable Type export format and then use the MT importer in the latest release.
