Relocating a Subversion Working Copy URL
If your Subversion url has changed or you need to switch from using http to https, you can use the "svn switch --relocate" command to change your local working copy. This will help avoid doing a fresh checkout.
Make sure you are in the root directory of the repository. Here is an example of changing from HTTP to HTTPS:
svn switch --relocate http://account.svn.beanstalkapp.com/repo https://account.svn.beanstalkapp.com/repo
If you use TortoiseSVN, see this article for instructions.
