Migrating phpBB to NodeBB

I recently set about migrating an aging phpBB forum to NodeBB and ran into enough problems that I considered cancelling the whole project.

The phpBB exporter script has been updated various times, and I managed to find a fork which appears to work with phpBB 3.2. Unfortunately, it refused to install itself correctly and appeared to land in the wrong directory, so I had to manually clone the Github project into the expected subdirectory.

And bingo! The import worked, and after disabling/deleting unnecessary plugins and updating NodeBB to the latest branch, the majority of things were working as expected. A few things remain to be fixed, in particular navigating mongodb’s structure to perform a few custom replacements where the import script had trouble deciphering bbcode.

Fortunately StackOverflow provided a good start:

var bulk = db.getCollection('objects').initializeUnorderedBulkOp();
var count = 0;
db.getCollection('objects').find({$and: [{_key:{$regex: /^post:\d+$/}}, {content: {$regex: /<size size="150">(.*?)<\/size>/}}]}).forEach(function(entry){
    var newContent = entry.content.replace(/^<size size="150">(.*?)<\/size>/gm, "## $1");
    bulk.find( { _key: entry._key } ).updateOne( { 
        $set: { 'content': newContent } 
    if (count % 100 === 0) {
        // Execute per 100 operations and re-init
        bulk = db.getCollection('objects').initializeUnorderedBulkOp();
        count = 0;

// Clean up queue
if (count > 0)  bulk.execute();

Using this I was able to find and replace those tags which had been missed and replace them with valid markdown.

Changing Your phpBB3 Domain

If like me you’ve decided at some point to move your phpBB install to a new domain or location within a domain, there are a number of little hurdles to jump before you can successfully consider the move complete. Here’s my short one-two-three guide for getting your forum moved over to a new address.
