Although I use Git for anything open source we produce, all other code is still in a SVN repository. I use VisualSVN Server for the server side things. When upgrading it last week to the latest version, it mentioned that Apache SVN 1.10 had new compression options and it occurred to me that while I've upgraded working copy formats before, my SVN databases are probably still using whatever format they were created at. This article covers how to upgrade SVN repositories using the VisualSVN Server software.
According to the release notes, the current filesystem format version used by SVN is
8. We can either use the
svnadmin info command to view the version, or via a GUI by right clicking a repository in the Visual SVN Server Manager, selecting Properties from the context menu then accessing the Details tab.
