Had a family member move internationally for a promotion once. It was fine, but they're very social and I think the loss of social circle was pretty tough on them, and the new position didn't really lead anywhere else as fast as they'd hoped, eventually they took a lateral position change a few years later to get back home. That position turned out to be nothing like what they agreed to, and they left the company shortly after for a pay downgrade to a job in their original field that they actually enjoy. The experience with that international role probably helped them look better, but was by no means necessary for the role and level they ended up.

So it's doable, just be careful you don't move away from it all for just great expectations. Take it only on the merits of what it is right now and the immediate, tangible career benefits, not future trainings and projects, just what you're moving into right now. Stuff like that has a tendency to shift away from what you were promised very easily.
