breastfeeding questions

I'm ebf my 7 months old. He eats solids and therefore doesn't take the boob as much as he used to. I'm moving to another country next month and I'll need to pump and leave milk a few times. I don't know if I'll have enough to pump??
My second question is: I would love to breastfeed him until he's one. If he's only taking the boob about times a day now will I even have milk till he's one?
