+Upgrading from 0.3 or higher
============================
If you are upgrading from versions 0.3 or higher of SquirrelMail, you can
from scratch and configure your settings as if it was your first install.
NOTE: The new plugin architecture required the use of some functions which

1. Backup old install
sure to use the "-Rp" options. -R means recursive, and -p will save the
permissions in the directory.

Substitute version numbers and names as required.
$ cd /home/httpd/html

+ $ cp -Rp squirrelmail-1.2.6 squirrelmail-1.2.6.bak
2. Unarchive new SquirrelMail

Make sure that you are in your httpd document directory (/home/httpd/html)

A. Preferences
First, copy your preference data over to the new directory. Usually
this is ok, but if you are upgrading from anything less than 1.0.5, we
strongly suggest you let your users reset their preferences. There
were important security upgrades in 1.0.5 regarding preference files.
-
- $ cp squirrelmail-1.0.6.bak/data/* squirrelmail-1.2.0/data

+ $ cp squirrelmail-1.2.6.bak/data/* squirrelmail-1.4.0/data

+If at all possible, start the configuration process from scratch. It is
much less prone to missing configuration options than copying your old
configuration. Ideally, you should just run conf.pl to reconfigure
SquirrelMail. If you decide to copy your old config.php over, we strongly
recommend that you run conf.pl to make sure things are correct and then save
the config file.
- $ cp squirrelmail-1.0.6.bak/config/config.php squirrelmail-1.2.0/config
+ $ cp squirrelmail-1.2.6.bak/config/config.php squirrelmail-1.4.0/config
C. Copy plugins
Like SquirrelMail, plugins are frequently updated for improvements, as well
as to make them compatible with new SquirrelMail releases. It is suggested
-that you download a new plugins archive at the same time you download your
-SquirrelMail install, and that you install your plugins fresh (it's easy,
-don't panic!).
+that you download new versions of your plugins at the same time you download
+your SquirrelMail install, and that you install your plugins fresh (it's
+easy, don't panic!).
-If you prefer to just copy your old plugins over (if it's the same version
-or if you are lazy), you may do so. If you notice irregularities with the
-plugins under the new SquirrelMail, try installing new versions of the
-plugins.
+You should not try replacing plugins that are already included in SquirrelMail
+package. Download latest versions of plugins that are not included in new
+SquirrelMail package or copy them from older SquirrelMail install.
- $ cp -Rp squirrelmail-1.0.6.bak/plugins/* squirrelmail-1.2.0/plugins
-
D. Copy themes
If you've created or modified themes, you should copy just those to the new
SquirrelMail themes directory. To just copy them all over to the new
SquirrelMail installation, you can run one command.
- $ cp squirrelmail-1.0.6.bak/themes/* squirrelmail-1.2.0/themes/
+ $ cp -ui squirrelmail-1.2.6.bak/themes/* squirrelmail-1.4.0/themes/
-(While you are at it, you should send them to us! We might add them to the
-themes in the standard install!)
+When -u flag is used, command copies only missing and newer files.
+When -i flag is used, command asks for confirmation before replacing
+existing files.
4. Change permissions
example, we assume that user "nobody" and group "nobody" are the web server
as is often the case with Apache.
- $ cd squirrelmail-1.2.0
- $ chown -R nobody.nobody data
-
+ $ cd squirrelmail-1.4.0
+ $ chown -R nobody:nobody data
+
See INSTALL for alternate userid/groupid pairs. Additionally, if "chown
-user.group" doesn't work, you can use "chown user" and "chgrp group"
+user:group" doesn't work, you can use "chown user" and "chgrp group"
instead. See the man pages for these commands for more information.
