4 As Moodle grows, there are changes to the code and
5 sometimes changes to the database structures.
7 Moodle is able to upgrade its own databases, using
8 information in files called version.php. There is
9 one of these for the main tables (in this directory)
10 and one for each module.
12 When upgrading from any previous version of Moodle,
13 all you normally will need to do is this:
15 1) Make a backup of your current Moodle installation
16 in the unlikely case that something goes wrong and
17 you need to restore the older version.
19 2a) If you are using CVS, just go the root directory
20 and type "cvs update -d" (or whatever the equivalent
21 is on your non-Unix server).
25 2b) Remove the current installation, and then unpack
26 the new tar or zip file in the same location.
27 Make sure you copy the config.php file from your
28 old installion to the new installation (or make a
29 new one by editing config-dist.php).
31 3) Visit the home page of your installation. Moodle
32 will automatically detect the new version and perform
33 any database upgrades that might be necessary.
35 If all goes well (no error messages) then you can just
36 go on using Moodle normally.
38 If you have problems with this procedure, let me know.
