How do you migrate a WSS2 web site to another server running WSS3?

SharePoint

I’ve got two servers running Windows SharePoint Services.

Server ‘A’ is running 2.0, server ‘B’ is running 3.0.

I’d like to migrate a single web site from A to B.

I found this KB article - How to move a Windows SharePoint Services Web site from one server to another by using FrontPage 2003, and I thought I’d be clever and use SharePoint Designer to try and do a similar thing, but it doesn’t work.

You can backup the 2.0 site ok, but when you connect to the empty 3.0 site, the restore function expects a different file type.

It does seem a reasonable thing to want to do, and it’s annoying that there doesn’t appear to be an obvious solution.
