Here are all of the changes so far (we'll keep updating throughout the show):
Kevin Owens to SmackDown
Kevin Owens comes to SmackDown as the United States Champion - and beardless. After SmackDown lost Intercontinental Champion Dean Ambrose to Raw, it was a move that had to happen.
Sami Zayn to SmackDown
Sami Zayn announced his arrival by saying he's "finally' made it to SmackDown, and he should be a much better fit on Daniel Bryan's roster than he was on Raw.
The Shining Stars to SmackDown
Fans likely remember the seemingly never-ending Shining Star faux-tourism skits every week before they arrived on Raw, but they did very little once they actually made it to the show. They arrived Tuesday to take out American Alpha after a tag match, and like Kevin Owens, had a new look.
Jinder Mahal to SmackDown
Rob Gronkowski hit Jinder so hard at WrestleMania 33 he flew from Raw to SmackDown.
Charlotte to SmackDown
Charlotte is the most decorated female performer in WWE currently, but she needed new surroundings. She had already wrestled in nearly every type of match imaginable with Sasha Banks and delivered a few great matches with current Raw Women's Champion Bayley - but you can only face the same two or three people each week for so long. On SmackDown, Charlotte has a number of great potential opponents in Becky Lynch, Natalya and Naomi.
Tamina to SmackDown
Tamina Snuka hasn't been seen in action since undergoing knee surgery last May.
Sin Cara to SmackDown
With Kalisto moving to Raw, this means there's no Lucha Dragons reunion in the works.
SmackDown lost a few midcarders to Raw in the shakeup, and Sin Cara can be a valuable asset early in shows even if he's out of any title picture.
Rusev to SmackDown
"Handsome" Rusev is currently out with a shoulder injury that forced him to miss WrestleMania, but he was an underrated role player on Raw who has the potential to be a main-event contender.
Lana to SmackDown
Lana was introduced as a SmackDown acquisition apart from Rusev, and even had a small video package hyping her arrival - suggesting that we could be seeing the solo debut of Lana as a wrestler.
The New Day to SmackDown
The New Day had nothing left to accomplish on Raw, but they were still one of the most entertaining acts on the roster. Their arrival lends legitimacy to the SmackDown tag division.
