-Note that if at all possible, start the configuration process from scratch.
-It is less prone to missing configuration options than copying your old
-configuration. The ideal solution would be to copy your users' preference
-files, and then run conf.pl to re-configure SquirrelMail (without using the
-old config file). If you do copy the config.php file, you will want to run
-conf.pl and check for new options.
+C. Copy plugins
+
+Like SquirrelMail, plugins are fequently 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!).
+
+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.
+
+ $ cp -Rp squirrelmail-0.4.bak/plugins/* squirrelmail-0.5/plugins
+
+D. Copy themes
+
+If you've created or modified themes, you should copy just those to the new
+SquirrelMail themes direcory. To just copy them all over to the new
+SquirrelMail installation, you can run one command.
+
+ $ cp squirrelmail-0.4.bak/themes/* squirrelmail-0.5/themes/
+
+(While you are at it, you should send them to us! We might add them to the
+themes in the standard install!)
