I am able to restored my Database, Thank you. But can you please tell me how should I restore my Plugins. And How should I find out which plugin not support version 4.5.
No, You have to run individual upgrade script for individual plugin. Some plugin provide give upgrade script along with updated plugin. Some plugin provider handle it automatically. So, contact with plugin provider if they have upgrade script or not!
If you need those plugin then you have to upgrade with those plugin, right? I would prefer you to upgrade to latest version with default plugins first, then include other plugins 1 by 1, and check if everything okay.
