I have to read through various research papers and during the course I have to highlight and annotate. But if I rename the file later or change machine the highlights and annotations will be missing since they are stored separately. How can I preserve these highlights/annotations created in Okular if I change machines in the future?

Since KDE 4.2, Okular has the "document archiving" feature. This is an Okular-specific format for carrying the document plus various metadata related to it (currently only annotations). You can save a "document archive" from the open document by choosing File → Export As → Document Archive. To open an Okular document archive, just open it with Okular as it would be e.g. a PDF document.
Since Okular 0.15 you can also save annotations directly into PDF files. This feature is only available if Okular has been built with version 0.20 or later of the Poppler rendering library. You can use File → Save As... to save the copy of the PDF file with annotations.
