UPGRADING instructions
|
|
|
|
|
======================
|
|
|
|
|
|
|
|
|
|
Follow these instructions if upgrading from a previous version
|
|
|
|
|
of Roundcube Webmail. We recommend to carefully backup the existing
|
|
|
|
|
installation as well as the database before going through the following steps.
|
|
|
|
|
|
|
|
|
|
Using the update script
|
|
|
|
|
-----------------------
|
|
|
|
|
There is a shell script (for unix based systems) that does the job for you.
|
|
|
|
|
To use it, unpack the archive of the new Roundcube version to a temporary location
|
|
|
|
|
(don't replace the Roundcube installation you want to update)
|
|
|
|
|
and cd into that directory. From there, run the following command in a shell:
|
|
|
|
|
|
|
|
|
|
./bin/installto.sh <TARGET-FOLDER>
|
|
|
|
|
|
|
|
|
|
For <TARGET-FOLDER> you specify the path to the Roundcube installation
|
|
|
|
|
which should be updated. The update script will then copy all new files to the
|
|
|
|
|
target location and check and update the configuration and database schema.
|
|
|
|
|
After all is done, the temporary folder with the new Roundcube files can be
|
|
|
|
|
removed again.
|
|
|
|
|
|
|
|
|
|
WARNING: See Post-Upgrade Activities section below.
|

|

|
|
|
|
|
|
|
Updating manually
|
|
|
|
|
-----------------
|
|
|
|
|
If you don't have shell access to the Roundcube installation or if not running
|
|
|
|
|
it on a unix system, you need to do the following operations by hand:
|
|
|
|
|
|
|
|
|
|
1. Replace index.php and all files in
|
|
|
|
|
- ./bin/
|
|
|
|
|
- ./SQL/
|
|
|
|
|
- ./program/
|
|
|
|
|
- ./installer/
|
|
|
|
|
2. Replace the configuration defaults files:
|
|
|
|
|
- config/defaults.inc.php
|
|
|
|
|
- config/mimetypes.php
|
|
|
|
|
3. rsync the contents of the following folders from your installation
|
|
|
|
|
directory into the target folder:
|
|
|
|
|
./skins/
|
|
|
|
|
./plugins/
|
|
|
|
|
4. Run `./bin/update.sh` from the commandline OR
|
|
|
|
|
open http://url-to-roundcube/installer/ in a browser and choose "3 Test config".
|
|
|
|
|
To enable the latter one, you have to temporary set 'enable_installer'
|
|
|
|
|
to true in your local config/config.inc.php file.
|
|
|
|
|
WARNING: See SQLite database upgrade below.
|
|
|
|
|
5. Let the update script/installer check your configuration and
|
|
|
|
|
update your config files and database schema as suggested by the updater.
|
|
|
|
|
5. Update dependencies by running `php composer.phar update --no-dev`
|
|
|
|
|
7. Make sure 'enable_installer' is set to false again.
|
|
|
|
|
8. See Post-Upgrade Activities section.

Post-Upgrade Activities
|
|
|
|
|
-----------------------
|
|
|
|
|
1. Check .htaccess settings (some php settings could become required)
|
|
|
|
|
2. If you're using build-in addressbook, run indexing script /bin/indexcontacts.sh.
|
|
|
|
|
3. When upgrading from version older than 0.6-beta you should make sure
|
|
|
|
|
your folder settings contain namespace prefix. For example Courier users
|
|
|
|
|
should add INBOX. prefix to folder names in main configuration file.
|
|
|
|
|
4. Check system requirements in INSTALL file.
|
|
|
|
|
|
|
|
|
|
SQLite database upgrade
|
|
|
|
|
-----------------------
|
|
|
|
|
Versions older than 0.9 were supporting SQLite v2 only. Newer versions require
|
|
|
|
|
database in v3 format. The best what you can do is to convert database file
|
|
|
|
|
to the new format using command line tools:
|
|
|
|
|
|
|
|
|
|
sqlite OLD.DB .dump | sqlite3 NEW.DB
|
