We are planing to migration our projects version controlled by clear case into SVN. And I have tried the SVNImporter which is provided by polarion. Its ok for small vob migration. But when the vob is larger (200mb), I will get the heap out of memory error (I have set the -Xmx = 1024m ), and it is slow to do that process.
Any one has some experience on CC to SVN migration and known some other open source tools which will work for large clearcase vobs? Or any suggestion/best practice can share with will be much appreciated.
Update: we need the history of files, branch, tag on clear case
The only workaround would be to try and make the import incremental wuith the SVNImporter.
For instance, import only a part of the cc2svn dumped vob (by top sub-folders, which is useful if those folders represents a component): one svn repo per component can be easier to manage (and import) than a giant svn repo.
