As far as I can see, you should make a backup of your database and old wp installation first. Copy the old b2config.php to a save place, then remove your old 0.71 files and install the 0.72 in the same directory. Copy the b2config.php back into the directory. Copy wp-config.sample.php to wp-config.php and edit it according your needs (normally you just have to change your database settings there). Oh, and be sure to change the table prefix from “wp_” to “b2_”.
The next step is to call https://yourdomain.com/yourdirectory/admin/wp-71-to-72-upgrade.php (not sure about the exact filename, I just recall it from memory… you will have to look up the correct filename, but it should be clear).
The main difference between 0.71 and 0.72 is that most of the settings are saved in the database instead of a configuration file. So, the upgrade will import your old settings out of b2config.php to the new database tables. After the upgrade you can remove b2config.php, and you should remove the installation and upgrade files.
Hope that helps. Please be sure to double-check all the above. It’s just recalled from my memory, I just did the upgrade one single time so far ??
