There was some configuration issue. When I contacted the developer, they immediately replied and solved. As my server response time is low, I got so many issues in migrating. Though it is my server issue, developer ‘Panayiotis Halouvas’ helped me to solve all the problems. Panayiotis Halouvas had replied to all my mails (nearly 25 mails) and had shown interest to keep me satisfied with his support. Now, my site is fully migrated to Joomla 3.2.2. It is because of SP upgrade and their support.
If there is option to give 100 stars, I will definitely give them for SP Upgrade. It is worth to your money.
Thanks to SP Upgrade and Panayiotis Halouvas.
