Yes it should be possible. Just make sure that you're using a Thunderbolt cable (and at that, a Thunderbolt 2 cable only). In addition to the Apple TB2 to TB3 adapter. Sometimes people plug in a miniDisplayport cable and are frustrated it doesn't work when it needs to be a Thunderbolt cable (TB2 and miniDP are the same connector, but have different capabilities). And the Apple TB2 to TB3 has a female TB2 port and a male TB3 plug so the TB3 part has to go to the MBP with TB3 and then you plug the TB2 cable into the TB2 ports.
