# Upgrading

Pootle can easily be upgraded to newer versions. Here are some tips to make the process easier.

Familiarize yourself with important changes in Pootle over the versions. If you are upgrading to Pootle 2.x from Pootle 1.x, have a look at the Database Migration page first, although some of the issues on this page could still be relevant.

Check the Quickstart instructions for the newer version, and ensure that you have all the dependencies for the newer version.

Always make backups of all your translation files (your whole `PODIRECTORY`) and your custom settings file. You can synchronize all your translation files with the database using the syncdb mangament command before you make your backups.

Make a backup of your complete database using the appropriate dump command for your database system.

If you are upgrading from a version of Pootle that uses localsettings.py then you want to make sure your configuration file is read when Pootle starts. For more information, read the Customizing Settings section.

You might want to look for any new available settings in the new version that you might want to configure.

Once you have the new code configured to run in your web server using the correct settings file, Pootle will perform the necessary upgrade when the first page is requested.

Note

For certain upgrades this automated upgrade might take a long time. In such cases you might prefer to perform the upgrade from the command line before taking the server live. Do this with the updatedb management command.

After a successful upgrade, consider clearing your cache. For users of memcached it is enough to restart memcached. For users of the default database cache, you can drop the pootlecache table and recreate it with:

    $ pootle createcachetable pootlecache

## Custom Changes

If you made any changes to Pootle code, templates or styling, you will want to ensure that your upgraded Pootle contains those changes. How hard that is will depend entirely on the details of these changes.

Changes made to the base template are likely to work fine, but changes to details will need individual inspection to see if they can apply cleanly or have to be reimplemented on the new version of Pootle.

Since Pootle 2.5 `customization of style sheets and templates` have become much easier to seperate from the standard code. If you are migrating to Pootle 2.5+ then use this opportunity to move your code to the correct customization locations.
