I had to restructure the projects in SVN as it was not added as per the recommended repository structure (no tags, branches and trunk folders). However after moving projects to the new structure we have lost the history of all the files.
How can I get back the history of all the files?
I created the copy of the Dev => Project1 to Project1 => trunk. And Deleted the Dev directory from SVN.
Update: I got the history back after performing the clean operation using TSVN.
