A script to migrate from PostfixAdmin to Modoboa

modoboa-pfxadmin-migrate

A script to migrate from PostfixAdmin to Modoboa. It has been tested against versions 2.3.3 and upper.

Note

This script is only suitable for a new Modoboa installation.

Installation

Install this extension system-wide or inside a virtual environment by running the following command:

$ pip install modoboa-pfxadmin-migrate

Edit the settings.py file of your modoboa instance and add modoboa_pfxadmin_migrate inside the MODOBOA_APPS variable like this:

MODOBOA_APPS = (

  # End of list
  'modoboa_pfxadmin_migrate',
)

Then, add a new database connection named pfxadmin into the DATABASES variable corresponding to your PostfixAdmin setup:

DATABASES = {
    "default" : {
        # default connection definition
    },
    "pfxadmin" : {
        "ENGINE" : "<engine>",
        "NAME" : "<database name>",
        "USER" : "<database user>",
        "PASSWORD" : "<user password>",
    }  
}

This connection should correspond to the one defined in PostfixAdmin's configuration file.

Run the script

You are now ready to start the migration so run the following commands:

$ cd <modoboa_instance_dir>
$ python manage.py migrate_from_postfixadmin -s <password scheme>

<password scheme> must be replaced by the scheme used within postfixadmin (crypt most of the time).

Depending on how many domains/mailboxes your existing setup contains, the migration can be long. Just wait for the script's ending.

The procedure is over, edit the settings.py file and:

• remove the pfxadmin database connection from the DATABASES variable
• remove 'modoboa_pfxadmin_migrate' from the MODOBOA_APPS variable

You should be able to connect to Modoboa using the same credentials you were using to connect to PostfixAdmin.

postfixadmin migration script don´t create amavis records

From @controlcde on February 1, 2015 19:17

I´ve configured modoboa before I fire up the postfixadmin migration script but after a sucessful import the needed records in the amavis database are missing.

Copied from original issue: modoboa/modoboa#681

Script fails while importing a user

Hello there,

i created a fresh install of modoboa and created a database on the localhost and included the database from the pfxadmin-server.

It starts to work fine, but it finishes with the following:

---- snip here ---

There is only one user with this log in, but with a couple of aliases.

And this user is also superadmin in the admin-table.

If i delete the user in the admin-table the script stops directly.

If needed, i could provide access to the server.

pfxadmin is Version 3.1

Maybe the database-structure changed a bit?

Any help appreciated!

Thanks in advance

Greetings

Marcel

Script failed if quota is set

If at least one mailbox has a quota defined in the old postfixadmin install, the script failed with the following error:

Script Failure on Ubuntu 20.04 LTS New Modoboa Install

I was asked several months ago to evaluate email solutions for a small local company. After evaluating several options, I settled on Modoboa as a replacement for their current Postfix/Dovecot system. It took a lot of convincing. The most important issue for them was whether I could migrate their current email accounts and mail to Modoboa. I understand that there are two scripts, modoboa-pfxadmin-migrate and modoboa-imap-migration. I chose to use modoboa-pfxadmin-migrate. I followed the instructions for installation and usage. I immediately encountered errors.

Ubuntu 20.04 LTS uses Python3. The command "python" is aliased to "python3"

Upon executing the script, I received the following errors;

postfix doesn't accept incoming connections on ipv6; connection reset by peer

inet_protocols = ipv4

to:
inet_protocols = all

to make it work.
