Hard to say, really. Do you know if they used to get lots of figs from it? Were they good? Do you have enough space? Why did they want to get rid of it?
It probably won't make a nice "tree" shape if it re-grows after you trans plant it, it will be sort of a large shrub with many trunks. This is fine because it makes the figs easy to harvest if it bears for you. But it takes up more room in your garden, too.
If you decide to dig it, wait until it gets cold enough that the plant loses all it's leaves and is dormant. Then, get the largest root ball you can possibly handle. Dig around, slide it out onto a tarp and drag it to where you're going to plant.
