1 | Upgrading from 0.3 or 0.4 |
2 | ========================= |
3 | If you are upgrading from versions 0.3 or 0.4 of SquirrelMail, you can use this |
4 | guide to make the transition a bit smoother. If you have been using a previous |
5 | version (0.1 or 0.2), it is suggested that you just start from scratch and |
6 | configure your settings as if it was your first install. |

8 | NOTE: The new plugin architecture required the use of some functions which are |
9 | not in all versions of PHP4. You will need at least PHP4 beta2. If you need to |
10 | upgrade please go ahead and install the latest release version of PHP4. |

12 | 1. Backups |
13 | =========== |
14 | Make a backup of your current SquirrelMail directory. If you use "cp", be sure |
15 | to use the "-Rp" options. -R means recursive, and -p will save the permissions |
16 | in the directory. In this example, we assume that your httpd document directory |
17 | is /home/httpd/html. |
18 | |
19 | $ cd /home/httpd/html |
20 | $ cp -Rp squirrelmail-0.4 squirrelmail-0.4.bak |
21 | |
22 | |
23 | 2. Unarchives Squirrelmail-0.5.tar.gz |
24 | ====================================== |
25 | Make sure that you're in your httpd document directory (/home/httpd/html) and |
26 | then unarchive the squirrelmail archive (whatever the filename is): |
27 | |
28 | $ tar -zxvf squirrelmail-0.5.tar.gz |
29 | |
30 | |
31 | 3. Copy backups in place |
32 | ========================= |
33 | Here is the main part. There are two parts to this step: copy preferences, |
34 | and copy config details. The preference files are backwards compatible, so it |
35 | is fine to copy the old user preferences into the new directory. However, the |
36 | configuration file has changed quite a bit, so you will want to be sure to run |
37 | the configure script (conf.pl) to set up any new config details. |
38 | |
39 | First, copy the files in place: |
40 | |
41 | $ cp squirrelmail-0.4.bak/data/* squirrelmail-0.5/data |
42 | $ cp squirrelmail-0.4.bak/config/config.php squirrelmail-0.5/config |
43 | |
44 | Note that if at all possible, start the configuration process from scratch. |
45 | It is less prone to missing configuration options than copying your old |
46 | configuration. The ideal solution would be to copy your users' preference |
47 | files, and then run conf.pl to re-configure SquirrelMail (without using the |
48 | old config file). If you do copy the config.php file, you will want to run |
49 | conf.pl and check for new options. |
50 | |
51 | |
52 | 4. Change permissions |
53 | ====================== |
54 | The web server must have write permission to the data directory. In this |
55 | example, we assume that user "nobody" and group "nobody" are the web server |
56 | as is often the case with Apache. |
57 | |
58 | $ cd squirrelmail-0.5 |
59 | $ chown -R nobody.nobody data |
60 | |
61 | |
62 | 5. DONE! |
63 | ========= |
64 | That should be all! The most important part is copying your users' preference |
65 | files back into the new data directory. This will insure that your users will |
66 | have their old preferences. |
