I think one viable way would be for the script to convert those as well in the process of migration, or at least afterwards. I thought of rewrites earlier but that won't work as the DB structure will be different. The migration process could create a temporary table (?) correlating a given message (and topic) in both the SMF and Flarum databases and afterwards be used to lookup the correct values to be replaced in URLs.

    Hello everybody.
    Just to say thanks for your interest in this migration script. Although I haven't written any updates for a long time, I want to clarify that I haven't abandoned at all the development and I'm just waiting for the first stable to be released to complete the work and merge some fixes I coded in the last few months.
    Once the first stable is out, I'll get back to work ?
    Thanks for sharing your experiences!

      Thanks for your work and your comment! I had read another comment earlier where you mentioned waiting for a stable release, but in case it takes a lot of time and if you want something tested, let us know!

        acseven It's interesting that I found my attempt here. I'm still working on it to include posts.

        However, this script might not work for everyone, as my current backend is a heavily modified SMF, that too a very old one. It's 1.1.18 to be precise.

        For SMF 2.x, this won't work as there are a lot of changes in those SMF versions.

            SHC I found it a while ago and remembered to add it to the thread, as it might come handy when the first stable release of flarum is released. But thanks for the additional notes!

              Hello everybody. After a long time I passed by to... say goodbye. Despite the fact I still think that flarum is the most promising php-based web forum platform, we cannot afford to wait any longer for the first stable to come out.
              SMF2 is just too old, as platform and as concept, and we don't want to wait an undefined amount of time for Flarum to be ready.
              Don't get me wrong, we fully understand that this is a voluntary project and that the lead developers have a real life. Kudos for what they accomplished so far. That said, we're going to migrate to another product by the end of the year.
              Before going I gladly share some more line of code with those who might migrate from SMF2 to flarum in the future.

              acseven BUT the internal URLs are not being corrected. That's to be fixed with rewrites, I guess, but it would be great if the URLs could migrate to the new Flarum URL...

              I have implemented (more than a year ago, please test it carefully) this function, that shall be added to the alternative version of the script and called from there.
              The function convert_links converts all internal links in each posts to the new format.
              The import parameters are the message body (in $text) and the post counter.
              This does not help with the search engines (something else would be needed, that returns a HTTP 301 error together with the new URL, but this would be a long story...) but at least allows the forum members to jump across posts with ease.

              function convert_links($text,$post_counter)
{
        $discussion_id = 0;
        $post_id = 0;
        $replacements = 0;

        // Example: http://www.smf2forum.bla/index.php?topic=25645.msg276350#msg276350
        // Regular expression - www.forum.bla is of course a totally made up name. Substitute it with your site URL
        $regexp = '#http:\/\/www\.forum\.bla\/index.php\?(topic=(\d+))+(\.msg(\d+))+(\#msg\d+)#is';
        
        // There are no internal links in this post, return it as it was
        $results = preg_match_all($regexp,$text,$matches);
        if (!$results) return $text;
    
        // Do the actual replacement using rhe regular expression
        // As before www.forum.bla is totally made up. Substitute it with your site URL.
        // It might still be the smf2 website name, or something new.
        $text = preg_replace($regexp,"http://www.forum.bla/d/$2/$post_counter",$text);
        return $text;
}

              All the best to this community and to Flarum.
              If you have questions post here, I might pass by sometimes to check on this project every so often...

                Thank you for leaving your insight on this and for the additional script, which you definitely be useful when time comes. It's unfortunate that the stable version of Flarum's core is taking a while to be completed, but it is what it is. In my particular case I don't have any time critical deadline for moving from SMF, so I prefer to wait until the first stable version and see what is actually possible to migrate then.

                Thanks a lot for all the work in the initial script!

                wolfman I run an old SMF1 forum which i want to migrate to Flarum - or at least like @marcozambi test Flarum with the original content from SMF1. This script seems to be a good starting point for an SMF1-migration script. I will look at this in a couple of days.

                Well, couple of days turned into almost 2000 days! But better late then never i guess! 😉 So i finally migrated my SMF1 forum this morning with about 25k topics/336k posts to Flarum and everything went fine so far!

                Instead of using the script from @marcozambi as initially intended, i went with the script provided by SHC (see also https://discuss.flarum.org/d/7290-migration-for-a-very-large-smf-forum and https://github.com/sriharshachilakapati/JGO-Flarum-Migration) as the basis for my migration script as it better fitted my needs.

                I added some additional functionality to the Script like migrating avatars or importing file-attachments to FoF Upload via Flarum-API, converting internal links, replacing Smileys with Emojis or migrating boards to secondary tags. While some adjustments might be of wider use, others are oddly specific for my migration!

                However, if somebody is still running a SMF-Forum and wants to migrate to Flarum (highly recommended!), this might be a good starting point for your migration: https://github.com/wolfgang-demeter/smf2flarum
                It will however not run out of the box for you!

                I migrated a SMF1 Forum. I do not know if this will work or is compatible with SMF2!

                      Thanks a bunch for this, I'm now testing it to migrate an SMF v2.x forum. Although there are some parts specific to the forum being migrated (e.g. groups correspondance a significant one), so far so good.

                      Migrated so far:

                      • Categories: ok, even though no primary tags are assigned (planning to do that manually).
                      • Boards: ok, same as above.
                      • User (13k): Looks ok, needs verification.

                      A few notes for others testing this as well:

                      • Script doesn't take in account a prefix for Flarum db table names, this has to be fixed manually throughout the code if you have one (or simply don't set one when installing Flarum).
                      • Many SMF table fields aren't the same (SMF v1 vs SMF v2). E.g. memberName vs member_name

                        Also a little quirk i just stumbled upon on my migrated forum. The search was incredible slow! Seems that through the numerous test-migrations on the live-environment and the script only deleting entries from the posts table and other tables when re-run there was a MySQL FULLTEXT-index with numerous gigabytes (/var/lib/mysql/yourdatabasename). After an OPTIMIZE TABLE on all tables the index shrunk considerably and the search is a lot snappier. The OPTIMIZE TABLE can take a long time. So be aware of that.

                        Hi,
                        Hoping to get some help with this; I can't find a way of finding out why the API endpoints aren't accessible.

                        Do you have any pointers on this?

                        Fatal error: Uncaught GuzzleHttp\Exception\ClientException: Client error: `GET https://mydomain/public/flarum/api/discussions` resulted in a `404 Not Found` response:

                        Regarding my SMF 2.x forum migration, overall:

                        • Categories: now ok, needed to be revised.
                        • Boards: same as above.
                        • Users: Mostly ok, except for avatars (because of the API not being acessible)
                        • Forum posts/topics: trials were ok, except for attachments (same as above).

                          acseven Seems you haven't set your Flarum API-URL correctly!

                              Hello, I'm new here, I've just finished an installation, not without difficulty, but after several attempts, everything is working perfectly.
                              I'd like to migrate my SMF old forum, but I can't seem to configure the "smf2_to_flarum_settings.php" file correctly, as I'm having a database connection issue. Could you provide me with an example of what should be entered in this section, as I'm a bit stuck: $servername = "localhost"; // Server name for both SMF and Flarum DB.
                              Thank's in advance
