This procedure is compatible with any version greater or equal to 1.4. For an older version, ask for help on the forum.
First and foremost, please do check Piwigo current requirements. Especially if your Php / MySQL configuration is NOT sufficient, do not go further as the upgrade process will fail.
Step 1 - Package preparation
- Download the latest Piwigo release archive
- On your computer, extract the "piwigo" directory.
- Remove the default "piwigo/local" directory.
Step 2 - Database preparation (Recommended)
|Backup your current tables (3-5 min.)
If you are using a version from the PhpWebGallery 1.7 family or later, you can use the DB Backup plugin.
In any case, be sure to check the backup is exhaustive and has successfully completed (the result is sometimes truncated due to server limits).
[Our advice: unselect "Extended inserts" or reduce "Maximal length of created queries".]
[A] PhpMyAdmin recommended options.
Step 3 - File server preparation
|If you're running Piwigo 2.1 or higher, skip this step.
Backup your customized files only or all files (5 min.).
Step 4 - Gallery preparation
Step 5 - Cleaning
Remove all files of your current Piwigo installation, with the following exceptions, do NOT delete these directories:
Step 6 - FTP upload
- Use your standard FTP client to upload the new release, ie the content of the "piwigo" directory (extracted during step 1 and updated during step 3), into the previous Piwigo installation directory
- Check that your FTP client did not encounter any error
Step 7 - Database upgrade
Step 8 - Check the upgrade result
Your first controls could take time because you are not aware of all the changes (15-120 min.).
You will see a list of all your previous plugins; some of them have been fully integrated in the core (like Plugins Manager), others are now distributed (like LocalFiles Editor), but any desactivated plugin has been so for a good reason.
Try to find an upgrade first; the plugins tabsheets can help you.
For themes and templates, keep an admin page opened in your browser in case you need to reverse any of your tests.
Don't forget that your members or visitors can have a specific selected theme which is not compatible with your new release. You'd probably better have to reset their theme in the Admin users page.
Step 9 - Unlock your gallery
|You begin to be confortable with our last release, do not forget to unlock your gallery to give access to visitors (1 min).|
Step 10 - Post upgrade cleaning
Nothing (0 min.)
Nothing has to be removed after any upgrade.
The upgrade.php itself is not to be removed.
Remember that the "No upgrade required" message and the sign-on process are protecting your gallery.
