Hi Deepesh,

The ^/branches/main at r10 existed at ^/main at r6. To refer to
^/branches/main at r6, use a peg revision:

   http://svnbook.red-bean.com/nightly/en/svn.advanced.pegrevs.html

Also, it's better to give each branch a unique name when copying:

   svn copy ^/main ^/branches/release-1.x-prep

Regards,
Steve
