plagiarism - Same literature survey in first and final reports, Is it ok?

Is it considered bad to copy literature survey from 1st/initial report of the dissertation to the final report?

Does it count as self plagiarism?

Generally speaking one should include more recent researches, if any, related to the topic in the final report but what if there is only a 2-3 months period between two reports that happens for masters students in some countries (and in my case too).
