Hi Amit,
SCM-Manager stores repositories in the .scm path which is located in the home directory of the running user, for Linux this could be /usr/share/tomcat7/.scm/repositories/svn. So you have to copy your repositories to this directory. After that you start SCM-Manager, click on "Import Repositories" in SCM-Manager and select SVN in the appearing dialog box. Your repositories will be displayed immediately. Based on the experience with our support customers this should work without problems. If problems occur after all, you could contact us and we can work that out.
In the "Repository Types" screen of SCM-Manager you can define the repository directory and select an SVN compatibility mode. SCM-Manager 1.38 uses SVNkit 1.8.5, depending on your version of SCM-Manager the SVNkit version can differ.
with kind regards,
Daniel
