How can I "Save As" so I can use my Lifeograph diary on another computer?

I am curious if there's a "Save As" feature so that I could put my diary on a USB flash disk and then use it on a different computer after putting Lifeograph on it...then bring it back at the end of my trip, plug it in, and not have to deal with merging or exporting or anything like that. Is that possible?

If I just copy the file from its location to a USB drive and then copy it into the location on the new computer will that work? I see a "merge/synchronize" option but read that that's not working very well. It seems simpler just to take the file with me and use it on other Lifeograph-enabled computers (such as my laptop). How could I do that?

Thank you.
