SharePoint 2013 uses App Model for development. So you need to take a decision what approach you should follow.

Also SP 2013 encourages using CSOM as opposed to Farm Solutions.

If you have only limited time, then I think you can directly deploy 2010 solution and test what functionality is breaking, then try to fix only that.

  • Yes I know about App Model Client Side, but I don't wont to write again webpart, because my webpart has got about 2000 lines of code. But How can I deploy as 2010 instantion ?
