SMF to Flarum Converter

This will convert a SMF1-based forum to Flarum (v1.2.x).

This script is based on https://github.com/sriharshachilakapati/JGO-Flarum-Migration/

ATTENTION: This will not run out of the box! You most certainly have to modify the migrate.php script to match your needs!

Installation

Do not clone this into your SMF or Flarum installation directories! This is a standalone script and should be installed as such.

mkdir smf2flarum-migrate
cd smf2flarum-migrate
git clone git@github.com:wolfgang-demeter/smf2flarum.git .
composer install
cp settings.sample.php settings.php

Edit settings.php with the configuration for your SMF and Flarum installations. Also create an API-Token in your Flarum database. The Flarum-API will be used to migrate Avatars and Attachments.

You almost certainly have to edit some mapping-arrays and specific code-blocks to match your needs in migrate.php.

MySQL

If you have a lot of data to migrate, it could be necessary to increase the sort_buffer_size of MySQL.

nano /etc/mysql/mysql.conf.d/dev-for-flarum-migrate.cnf

Add the sort_buffer_size setting.

[mysqld]
sort_buffer_size = 1M

Restart MySQL

systemctl restart mysql.service

Migration

Clear Avatars & Attachments

It might be a good idea to clear existing avatars and assets/files from Flarum beforehand.

rm -v /path/to/flarum/public/assets/avatars/*.png
rm -rfv /path/to/flarum/public/assets/files/*

Run the script

Run the migration script. You have to confirm each step with yes or no.

php ./migrate.php

Run the complete migration without confirming each step beforehand.

php ./migrate.php --runall

If everything works as exptected, the output should look something like that:

Migrating categories: 8/8 (100%)
Migrating boards: 30/30 (100%)
Migrating users: 379/379 (100%)

(optional) BBCode 5 Star Rating by me

If you have 5 Star Ratings (⭐⭐⭐⭐⭐) in your posts you want to migrate. Adjust the function replaceBodyStrings() in migrate.php according to your needs.
