Why switch

Why people leave vBulletin

1
Looks frozen in time

Dense tables, tiny avatars, gray gradients. Members notice the year the design stopped evolving.

2
Mobile is barely usable

vBulletin's mobile experience was bolted on. Over 60% of forum traffic is now mobile.

3
No AI, no semantic search, no translation

Modern members expect what wpForo offers natively: AI search, auto-translation, smart moderation.

Why Discourse

What makes Discourse a great choice.

A modern, open-source forum built on Ruby on Rails with real-time updates, infinite scrolling, and a polished mobile experience. Discourse is the default choice for tech communities, open-source projects, and developer-focused organizations. Features built-in trust levels, automated moderation, and a mature plugin ecosystem. Official hosting starts at $50/month or self-host with Docker.

Complete migration

Everything we move from vBulletin to Discourse.

Nothing is left behind. Every post, user, and attachment makes the journey.

Posts & Threads

Every forum, category, thread, and post with full hierarchy preserved. BBCode and HTML converted to the target platform's format. Sticky threads, announcements, and poll data included.

Users & Profiles

All user accounts, display names, avatars, signatures, custom profile fields, user groups, and moderator/admin roles mapped to Discourse equivalents.

Attachments & Media

Every file attachment, inline image, and embedded media migrated with correct references preserved. No broken images, no missing files.

SEO & Redirects

301 redirects from every old vBulletin URL to the new Discourse URL. Your search rankings and inbound links are preserved.

Private Messages

User-to-user private conversations migrated with sender, recipient, timestamps, and read status intact. Your members keep their full message history.

Permissions & Groups

User groups, moderator assignments, banned users, and permission sets mapped to Discourse's permission model as closely as possible.

How it works

From submission to launch in 4 steps.

No upfront payment. No risk. You only pay once you've inspected and approved the result.

Common questions

Everything you're wondering, answered.

Which forum platforms do you support?
260 platforms, with 67,600+ from/to combinations. As sources we support every major forum: vBulletin 3/4/5, phpBB, MyBB, SMF, XenForo, IPS, IPB, bbPress, Vanilla, Discourse, NodeBB, Flarum, BuddyBoss, plus dozens of older or self-hosted systems. As targets, we move to wpForo, XenForo, phpBB, MyBB, bbPress, Vanilla, BuddyBoss, Discourse, Flarum, and NodeBB. We don't migrate to vBulletin because it's a deprecated commercial platform — but we happily migrate away from it.
Will I lose my SEO ranking after migrating?
No. We set up automatic 301 redirects from every old URL to its new counterpart on the target platform. Google preserves your rankings, and existing inbound links continue to work. We've migrated forums with millions of indexed pages without ranking loss.
Will my users keep their accounts and passwords?
Usernames, emails, and profile data move 1:1. Passwords from stand-alone forums (phpBB, MyBB, SMF and similar) typically can't be transferred because source and target use different hashing algorithms — this is technically impossible, no service can do it. We solve it with a one-click "send new passwords" tool that emails every user a fresh password on launch day. Where the algorithms match (e.g. some WordPress-based migrations), passwords transfer cleanly.
How long does the migration take?
Most migrations finish in 24–48 hours. Very large forums (250k+ posts) can take 3–7 days. Your live forum stays online the entire time — we migrate to a copy on our servers, you inspect, then we sync the final delta and switch over with zero downtime.
Why not just use a free migration tool?
Free automated tools are great for small, simple forums. They handle forums, topics, posts, basic users and attachments. They do not handle private messages, polls, custom user fields, signatures, BBCode conversion, 301 redirects, or theme migration. Most communities older than 2 years have all of these. That's where we come in.
What about my custom theme and modifications?
Standard themes can be re-built on most target platforms using their native templating. For highly custom themes or specific plugins, we offer a Premium tier that includes theme rebuild and feature setup. We'll quote both options in your free assessment.
What does "pay after success" actually mean?
You pay zero up front. We complete the migration, hand you access to the migrated forum, you inspect everything. If you're satisfied, you pay the quoted price. If the result doesn't match the agreement and we can't fix it, you don't pay. We've been operating this way since 2010 because we trust our work.
What if my exact from/to combination isn't listed?
Just ask. Our engineers have written custom migration scripts for dozens of obscure or self-built forums — some of them undocumented or 15+ years old. Submit a quote request and we'll respond with feasibility, price, and timeline within 6–12 hours.

The gConverter team helped me migrate a very old UBB (wwwthreads) database into a new XenForo installation. There were very few conversion issues on the first pass, and they cleaned them up quickly, exactly according to my request. I was concerned that this was...

“Great service, professional results, reasonable price”

We had our old forum running on phpBB and our new one on XenForo. Our old forum script and database were heavily customised. The standard conversion of the phpBB database and its merger with the existing new Xenforo database seemed to be impossible. gConverter.com...

“Invision Blog to WordPress”

I couldn't find anyone to do this conversion out there but these guys got it done and done right. With over 6500 entries covering 10 years it was important to get it right. If you are looking to convert from Invision Blog to Word Press then this is the way to go.
