[svn] Change SVN repository URL

My current SVN structure:

Path: .
URL: svn://someaddress.com.tr/project
Repository Root: svn://someaddress.com.tr
Repository UUID: -------------------------------------
Revision: 10297
Node Kind: directory
Schedule: normal
Last Changed Author: ----
Last Changed Rev: 9812
Last Changed Date: 2010-12-20 17:38:48 +0100 (Mon, 20 Dec 2010)

But our project (hence the SVN service) will work over sub.someaddress.com.tr instead of someaddress.com.tr (someaddress.com.tr will be redirected to somewhere else soon).

Since it is the development server, I could not be sure about what to do. Will I need to use svn switch or svn switch --relocate? Also, will I need to switch svn root someaddress.com.tr or the project branch someaddress.com.tr/project?

If you are using TortoiseSVN client then you can follow the below steps

Right-click in the source directory and then click on SVN Relocate

After that, you need to change the URL to what you want, click ok, it will be taking a few seconds.

Grepping the URL before and after might give you some peace of mind:

svn info | grep URL

  URL: svn://svnrepo.rz.mycompany.org/repos/trunk/DataPortal
  Relative URL: (...doesn't matter...)

And checking on your version (to be >1.7) to ensure, svn relocate is the right thing to use:

svn --version

Lastly, adding to the above, if your repository url change also involves a change of protocol you might need to state the before and after url (also see here)

svn relocate svn://svnrepo.rz.mycompany.org/repos/trunk/DataPortal
    https://svngate.mycompany.org/svn/repos/trunk/DataPortal

All in one single line of course.Thereafter, get the good feeling, that all went smoothly:

svn info | grep URL:

If you feel like it, a bit more of self-assurance, the new svn repo URL is connected and working:

svn status --show-updates
svn diff

If U want commit to a new empty Repo ,You can checkout the new empty Repo and commit to new remote repo.
chekout a new empty Repo won't delete your local files.
try this: for example, remote repo url : https://example.com/SVNTest cd [YOUR PROJECT PATH] rm -rf .svn svn co https://example.com/SVNTest ../[YOUR PROJECT DIR NAME] svn add ./* svn ci -m"changed repo url"

In my case, the svn relocate command (as well as svn switch --relocate) failed for some reason (maybe the repo was not moved correctly, or something else). I faced this error:

$ svn relocate NEW_SERVER
svn: E195009: The repository at 'NEW_SERVER' has uuid 'e7500204-160a-403c-b4b6-6bc4f25883ea', but the WC has '3a8c444c-5998-40fb-8cb3-409b74712e46'

I did not want to redownload the whole repository, so I found a workaround. It worked in my case, but generally I can imagine a lot of things can get broken (so either backup your working copy, or be ready to re-checkout the whole repo if something goes wrong).

The repo address and its UUID are saved in the .svn/wc.db SQLite database file in your working copy. Just open the database (e.g. in SQLite Browser), browse table REPOSITORY, and change the root and uuid column values to the new ones. You can find the UUID of the new repo by issuing svn info NEW_SERVER.

Again, treat this as a last resort method.
