I had a character in D1 that never really got very far, but I then started playing D2 with a fresh set of characters.
However, as I got more hooked on D2, I realized I REALLY wanted to experience the full story, so I grabbed my partner and we blazed through the entirety of D1.
As we were wrapping up, they told me that D1 veterans get special "legacy" cutscenes and dialogue for their characters, as they've already completed the D1 campaign.
Is there any way to get that in my D2 characters now that I've completed D1's missions/story? It would be really nice to have the effort I put into D1 show up in D2 as well. I'm on the Xbox One.
The Veterancy import was done back on August 1st, 2017.
Any changes to Destiny 1 characters beyond that point will not be reflected.
If you ran through D1 after D2's release, then you're definitely past the August 1st, 2017 date.
So, unfortunately, no, you cannot get Veterancy imports of your D1 characters in to D2.
