UPGRADING OR UPDATING DRUPA
INTRODUCTION
2 ------------
3 This document describes how to:
5 * Update your Drupal site from one minor 7.x version to another minor 7.x
6 version; for example, from 7.8 to 7.9, or from 7.6 to 7.10.
8 * Upgrade your Drupal site's major version from 6.x to 7.x.
10 First steps and definitions:
12 * If you are upgrading to Drupal version x.y, then x is known as the major
13 version number, and y is known as the minor version number. The download
14 file will be named drupal-x.y.tar.gz (or drupal-x.y.zip).
16 * All directories mentioned in this document are relative to the directory of
17 your Drupal installation.
19 * Make a full backup of all files, directories, and your database(s) before
20 starting, and save it outside your Drupal installation directory.
21 Instructions may be found at http://drupal.org/upgrade/backing-up-the-db
23 * It is wise to try an update or upgrade on a test copy of your site before
24 applying it to your live site. Even minor updates can cause your site's
25 behavior to change.
27 * Each new release of Drupal has release notes, which explain the changes made
28 since the previous version and any special instructions needed to update or
29 upgrade to the new version. You can find a link to the release notes for the
30 version you are upgrading or updating to on the Drupal project page
31 (http://drupal.org/project/drupal).
33 UPGRADE PROBLEMS
34 ----------------
35 If you encounter errors during this process,
37 * Note any error messages you see.
39 * Restore your site to its previous state, using the file and database backups
40 you created before you started the upgrade process. Do not attempt to do
41 further upgrades on a site that had update problems.
43 * Consult one of the support options listed on http://drupal.org/support
45 More in-depth information on upgrading can be found at http://drupal.org/upgrade
47 MINOR VERSION UPDATES
48 ---------------------
49 To update from one minor 7.x version of Drupal to any later 7.x version, after
50 following the instructions in the INTRODUCTION section at the top of this file:
52 1. Log in as a user with the permission "Administer software updates".
54 2. Go to Administration > Configuration > Development > Maintenance mode.
55 Enable the "Put site into maintenance mode" checkbox and save the
56 configuration.
58 3. Remove all old core files and directories, except for the 'sites' directory
59 and any custom files you added elsewhere.
61 If you made modifications to files like .htaccess or robots.txt, you will
62 need to re-apply them from your backup, after the new files are in place.
64 Sometimes an update includes changes to default.settings.php (this will be
65 noted in the release notes). If that's the case, follow these steps:
67 - Make a backup copy of your settings.php file, with a different file name.
69 - Make a copy of the new default.settings.php file, and name the copy
70 settings.php (overwriting your previous settings.php file).
72 - Copy the custom and site-specific entries from the backup you made into the
73 new settings.php file. You will definitely need the lines giving the
74 database information, and you will also want to copy in any other
75 customizations you have added.
77 4. Download the latest Drupal 7.x release from http://drupal.org to a
78 directory outside of your web root. Extract the archive and copy the files
79 into your Drupal directory.
81 On a typical Unix/Linux command line, use the following commands to download
82 and extract:
84 wget http://drupal.org/files/projects/drupal-x.y.tar.gz
85 tar -zxvf drupal-x.y.tar.gz
87 This creates a new directory drupal-x.y/ containing all Drupal files and
88 directories. Copy the files into your Drupal installation directory:
90 cp -R drupal-x.y/* drupal-x.y/.htaccess /path/to/your/installation
92 If you do not have command line access to your server, download the archive
93 from http://drupal.org using your web browser, extract it, and then ...
94 FTP client to upload the files to your web root.
96 5. Re-apply any modifications to files such as .htaccess or robots.txt.
98 6. Run update.php by visiting http://www.example.com/update.php (replace
99 www.example.com with your domain name). This will update the core database
100 tables.
102 If you are unable to access update.php do the following:
104 - Open settings.php with a text editor.
106 - Find the line that says:
107 $update_free_access = FALSE;
109 - Change it into:
110 $update_free_access = TRUE;
112 - Once the upgrade is done, $update_free_access must be reverted to FALSE.
114 7. Go to Administration > Reports > Status report. Verify that everything is
115 working as expected.
117 8. Ensure that $update_free_access is FALSE in settings.php.
119 9. Go to Administration > Configuration > Development > Maintenance mode.
120 Disable the "Put site into maintenance mode" checkbox and save the
121 configuration.
123 MAJOR VERSION UPGRADE
124 ---------------------
125 To upgrade from a previous major version of Drupal to Drupal 7.x, after
126 following the instructions in the INTRODUCTION section at the top of this file:
128 1. Check on the Drupal 7 status of your contributed and custom modules and
129 themes. See http://drupal.org/node/948216 for information on upgrading
130 contributed modules and themes. See http://drupal.org/node/895314 for a list
131 of modules that have been moved into core for Drupal 7, and instructions on
132 how to update them. See http://drupal.org/update/modules for information on
133 how to update your custom modules, and http://drupal.org/update/theme for
134 custom themes.
136 You may decide at this point that you cannot upgrade your site, because
137 needed modules or themes are not ready for Drupal 7.
139 2. Update to the latest available version of Drupal 6.x (if your current version
140 is Drupal 5.x, you have to upgrade to 6.x first). If you need to update,
141 download Drupal 6.x and follow the instructions in its UPGRADE.txt. This
142 document only applies for upgrades from 6.x to 7.x.
144 3. In addition to updating to the latest available version of Drupal 7.x core,
145 you must also upgrade all of your contributed modules for Drupal to their
146 latest Drupal 6.x versions.
148 4. Log in as user ID 1 (the site maintenance user).
150 5. Go to Administer > Site configuration > Site maintenance. Select
151 "Off-line" and save the configuration.
153 6. Go to Administer > Site building > Themes. Enable "Garland" and select it as
154 the default theme.
156 7. Go to Administer > Site building > Modules. Disable all modules that are not
157 listed under "Core - required" or "Core - optional". It is possible that some
158 modules cannot be disabled, because others depend on them. Repeat this step
159 until all non-core modules are disabled.
161 If you know that you will not re-enable some modules for Drupal 7.x and you
162 no longer need their data, then you can uninstall them under the Uninstall
163 tab after disabling them.
165 8. On the command line or in your FTP client, remove the file
167 sites/default/default.settings.php
169 9. Remove all old core files and directories, except for the 'sites' directory
170 and any custom files you added elsewhere.
172 If you made modifications to files like .htaccess or robots.txt, you will
173 need to re-apply them from your backup, after the new files are in place.
175 10. If you uninstalled any modules, remove them from the sites/all/modules and
176 other sites/*/modules directories. Leave other modules in place, even though
177 they are incompatible with Drupal 7.x.
179 11. Download the latest Drupal 7.x release from http://drupal.org to a
180 directory outside of your web root. Extract the archive and copy the files
181 into your Drupal directory.
183 On a typical Unix/Linux command line, use the following commands to download
184 and extract:
186 wget http://drupal.org/files/projects/drupal-x.y.tar.gz
187 tar -zxvf drupal-x.y.tar.gz
189 This creates a new directory drupal-x.y/ containing all Drupal files and
190 directories. Copy the files into your Drupal installation directory:
192 cp -R drupal-x.y/* drupal-x.y/.htaccess /path/to/your/installation
194 If you do not have command line access to your server, download the archive
195 from http://drupal.org using your web browser, extract it, and then ...
196 FTP client to upload the files to your web root.
198 12. Re-apply any modifications to files such as .htaccess or robots.txt.
200 13. Make your settings.php file writeable, so that the update process can
201 convert it to the format of Drupal 7.x. settings.php is usually located in
203 sites/default/settings.php
205 14. Run update.php by visiting http://www.example.com/update.php (replace
206 www.example.com with your domain name). This will update the core database
207 tables.
209 If you are unable to access update.php do the following:
211 - Open settings.php with a text editor.
213 - Find the line that says:
214 $update_free_access = FALSE;
216 - Change it into:
217 $update_free_access = TRUE;
219 - Once the upgrade is done, $update_free_access must be reverted to FALSE.
221 15. Backup your database after the core upgrade has run.
223 16. Replace and update your non-core modules and themes, following the
224 procedures at http://drupal.org/node/948216
226 17. Go to Administration > Reports > Status report. Verify that everything is
227 working as expected.
229 18. Ensure that $update_free_access is FALSE in settings.php.
231 19. Go to Administration > Configuration > Development > Maintenance mode.
232 Disable the "Put site into maintenance mode" checkbox and save the
233 configuration.
