Update 1.14.2010

1. Added in 1b to Section 1, reworded 1a to include information on Trevor Hannant's nice CMS Tutorial on how to upgrade to 4.0!

Update 1.15.2010

1. Added the statement below to Section 4, step 3a.

PLEASE delete all old vBulletin 3.x styles and revert to default or create a new default style if yours has ever been modified. I had an upgrade to perform last night that had CMS errors and with the old styles where as the forums and blog did not so it is known to cause issues if you do not delete your old 3.x styles and use default before you upgrade.

great guide, thank you, rated 5

In the structure, don't you have to tick:
Add DROP TABLE (as with vB3 backups!) ?

Glad it was helpful ;)

I have a screenshot provided, I do not check that with 90% of them that I do but on some I have to or it will not upload properly and it is noted to do so here: http://www.vbulletin.com/docs/html/m...myadmin_backup so try it either way first if it does not restore properly try leaving it unchecked and then give it a go.

Brilliant. This thread hasn't received the accolades it deserves. Rated 5.

I'll be upgrading shortly and really anxious but this thread will be my bible.

Thanks very much!

Your welcome, when I launch my new vB3 and vB4 sites I will be making this into a video tutorial including how to use BigDump and install mysqldumper ;).
