Hello, of course it's worth, unless you have special reasons not to do it. Yes the quickest way is to import via xml files. Depending on the number of the back articles it may be serious task, moreover it needs extra attention when, for example, there is formatting (italics, bold,...) within the abstracts. I think it's also worth considering having all content in one place, which may be desirable concerning external indexing services or search engines.
