If you switch your project from svn to hg, then the svn repository (which contains code AND wiki pages) is still available and read-only. No data is lost. The code and wiki pages can still be checked-out.
If you 'reset' your svn repository, then all of the code and wiki pages are deleted together: it's all one repository, and it's all destroyed. Does this make sense?
