Is there any tool or extension to do this. Or please advice how should i handle this? I tried using wordpress importer which did part of the posts but then开发者_JS百科 breaking down since it is too large. Please help me.

If your import stops halfway through an article, chances are that PHP reached its max_execution_time. You can change this value in your php.ini file, or break your import file in half, and resume from the article that was last imported successfully.
