Rovers begin the 2022/23 season with a trip to Valley Parade to take on the Bantams, with whom Miller spent the 2018/19 campaign on loan.
It was a year to forget, however, as they were relegated to the fourth tier after finishing bottom of League One.

Discussing the opening-day clash, Miller, who scored six goals in all competitions that season, said: “I couldn’t have asked for a better one, it’s a massive first game and it’s my old team.
"Obviously you want to do well and there’s a lot of fans there who will give me some stick, so hopefully I can show up.”
On the prospect of a frosty reception from the home fans on Saturday 30 July, he said: "I think it helps you, it gives you that extra five or 10 per cent when it gets tough and you need to dig in.
"If you can prove a few people wrong it’s all the sweeter.”
Miller scored 12 goals in League Two last term while on loan at Walsall, another former side he’s likely to come up against next season.
Mark Hughes’ Bradford have made several eye-catching signings this summer, including ex-Hull City captain Richard Smallwood.
The midfielder, 31, made 41 Championship appearances last term.
The Bantams are among the favourites for promotion from League Two next term along with Stockport County and Salford City, who also play Rovers in the opening month.
