If you realize that each file/directory in Subversion is uniquely identified by a 2-space coordinate system [url, revision] (given a checkout, you can use "svn info" to get its coordinates), then we can say that "svn up -r 39619" keeps the url changed and change the revision to whatever number you specified. In other words, you get the state of the working copy at whatever state it was that URL at that time. For instance, if you execute it within the trunk working copy, you will get the trunk at the moment 2.4.2 was released. On the other hand, "svn switch" moves the url: it basically "moves" your checkout from [whatever_url, whatever_rev] to [url_specified, HEAD], downloading the minimal set of diffs to do so. Given that /tags/r242 is a tag, it means that any revision is good, since nobody is going to commit into that directory (it will stay unchanged forever). So [/tags/r242, HEAD] is the same of any other [/tags/r242, REVNUM] (assuming of course that /tags/r242 was already created at the time of REVNUM). So basically you want svn switch to [/tags/r242, HEAD] if you don't plan on doing modifications, while you want [/branches/release24-maint, HEAD] if you want to work on the 2.4 branch. Going to [/branches/release24-maint, 39619] does not really serve many purposes: you have to find out and write 39619 manually, you still can't do commits since of course you want to work on the top of the branch, and you get less meaningful information if you later run "svn info" on the working copy (as you're probably going to forget what [/branches/release24-maint, 39619] means pretty soon, while [/tags/r242, NNN] is more clear).
