The Gers striker says the ghosts of last season's failure have been banished in style.
The Gers looked set to return to the top flight a year ago after an encouraging campaign, but were beaten in the play-off final by Motherwell to break hearts on the blue side of Glasgow.
This season, however, the club have come back with a vengeance and sealed their promotion on Tuesday night with a 1-0 victory over Dumbarton to return to the big time after four years away.
Miller, who has played a integral role in the club's success with 17 goals in 36 appearances in all competitions, believes that justice has been done with the title victory.
The 36-year-old told the club's website: "This is huge for the reason it gets us back to where we want to be, back into the top flight. It is this team’s first taste of success and one we have worked so hard for since day one when the manager came in.
"This was righting a wrong, we fell at the final hurdle last season and this year we have done it. Over the course of the season we have done it well, we have done it with brilliant football, style and it’s been enjoyable to play a part in.
"When you win leagues it is an accumulation of all the hard work you have put in over the season and when you win one it’s because you have deserved it, you have been the best team over the piece and that is undoubted."
Mark Warburton's side have undoubtedly deserved their triumph as they have been imperious all campaign long, losing just three of their 32 league matches.
There has already been talk of Rangers challenging at the top of the table in the Scottish Premiership next season, and winger Michael O'Halloran claimed on Tuesday that the club are ready to compete for trophies in the top flight.
For now, the club can now turn their attentions to adding more silverware before the end of the season, with the Challenge Cup final against Peterhead this weekend followed by the hugely-anticipated Scottish Cup semi-final clash with arch-rivals Celtic.
