Professional installation is available.
There is no automated upgrade script that is distributed with
Dada Mail. Usually, upgrades are very easy to do, so long as you
have performed an Advanced
Installation of Dada Mail. The reasoning is, all the custom
configuration of Dada Mail will be located in the outside config
file called, .dada_config.
All you need to do is to moved the old copy of Dada Mail out of the way, place the new copy of Dada Mail where the old copy was, tell it where the outside configuration file is and maybe change the permissions of a few files. So, let's get to it:
In your current Dada Mail installation, open up the,
Config.pm file that's located in the,
dada/DADA directory, which is in your
cgi-bin Find the variable called,
$PROGRAM_CONFIG_FILE_DIR and copy the value
saved.
Finding the, "$PROGRAM_CONFIG_FILE_DIR" variable and noting
its value.
If the value is, auto, as above, it means Dada
Mail is automatically finding the correct directory.
There's many ways you can move Dada Mail - I'm going to use my
FTP client, Transmit to rename the,
dada directory that's in the cgi-bin, to,
dada-old. When we're talking about moving Dada Mail,
we're talking about moving the directory, dada that
you've placed in the cgi-bin. This is the core Dada
Mail program.
Renaming the, "dada" directory to, "dada-old"
Once the old Dada Mail is out of the way, put a fresh copy of
the Dada Mail program into your cgi-bin. This is
basically Step #1 of the Advanced Installation of Dada
Mail - change the permissions of the mail.cgi file
to, 755 and visit the program in your web browser.
If you get the screen complaining about being installed and not
configured, we're on the right track.
The old Dada Mail in the renamed, "dada-old" directory and
the new Dada Mail in the, "dada" directory.
Open up the Config.pm that's now in the
dada/DADA directory, which is in your
cgi-bin and change the variable named,
$PROGRAM_CONFIG_FILE_DIR to the same value that was
set in your old copy of Dada Mail. Save the file to your server
and visit the mail.cgi script in your web browser.
Your Dada Mail should be back and upgraded.
If everything looks good, you may remove the old copy of Dada
Mail. If you want to test the new copy of Dada Mail and want to
easily rollback to the old version - just in case, just change
the permissions of the old copy of the, mail.cgi
script to, 644, so that Dada Mail is still on your
hosting account, but can't be executed.
Changing the old Dada Mail copy's, "mail.cgi" script
permissions to, "644"
The following technical documentation, located on the Dada Mail support site can help with difficult upgrades:
The
Upgrade FAQ also walks through an upgrade process, but
doesn't necessarily expect your to be using the outside config
file (.dada_config)
The Changelog will let you know most every change between versions of Dada Mail. It's a good thing to look at before an upgrade, if you're following a bug, or if you want to know if a new version of Dada Mail will be compatible with your current version.
