Relocate SVN repositories with SmartSVN

Today I had to move our SVN repositories to a new server, because the old one (an Xserve G5) is being emptied and then either sold or thrown away. So if you're interested in an early 2005 Xserve G5, send me a note. Anyway, relocating a repository was easier than I thought. A bit of reading and googling revealed the steps I had to take and to help you, I wrote them all down, sort of collected steps-to-take, and posted them on this page.
