We are looking at potentially acquiring a forum which is a Vbulletin 4.2.2 Forum with roughly 100,000 members 100,000 threads and 1,000,000 posts. Ideally we would like to convert from Vbulletin over to YAF as YAF is built in .net which is what our site is builit on. From my understanding the .net framework would give us much more integration capabilities with our current site then using a php forum. I have a few questions below and would love to see if you could help out with the answers to these questions.

-Has anyone out there converted over a Vbulletin forum to a Yaf forum?

-How difficult of a job would is this?

-Are there any tools available to help in the conversion process?

-Roughly how long of a project would you anticipate this to be on a forum this size?

Thanks so much for any help!

I converted my phpBB flavored forums to YAF a few years ago.

1- phpBB to yaf, yes, vbulletin, I haven't

2- time consuming, but not too difficult if you have full access to both database structures

3- not that i know of

4- i did 180k posts and it took a few hours, so i would have to say several hours for completion once tools are created

I exported my data into Excel spreadsheets, then read through the file and passed the values through to the sql database.

I wouldn't suggest going that method. It was quite a pain in the booty.

If I had to do it over, I would have created a sql staging table and then imported the information via sql instead.
