You mention that you're looking to
book an award flight in business (J), yes? Not upgrade an existing economy award flight? You used the term upgrade, but I'm not sure that's what you mean.
First off, have you checked UA's website? I see ample one-stop Saver J award availability SJO>FRA>ZRH in May 2018 for 75K miles each way, as long as you can leave on a Thursday. There are also a few flights leaving on Saturdays.
To get back you'd of course need to acquire another 75K miles, or you could always fly a low-cost carrier, as they often don't charge a premium for one-way tickets.
The most important tip I can share, though, is to
search and peruse the existing threads in the forum. It's filled with wisdom in the form of answers to questions just like yours. In fact this thread will almost surely soon be subsumed into an existing thread on Saver J availability.
