Weltman, 52, helped construct a Raptors team that reached the Eastern Conference Finals in 2016 and has qualified for the playoffs each of the past four seasons.
Asked for the number of employees fired Monday, Magic management declined to comment.
The Magic formally announced Tuesday that they have hired Jeff Weltman as their new president of basketball operations.
Hammond had been the Bucks' GM since 2008, drafting a fine young core of Giannis Antetokounmpo, Jabari Parker, Thon Maker and Malcolm Brogdon. "He has experience in everything from day-to-day operations to player development".
The Magic had been searching for a new front office head after firing Rob Hennigan in April.
And Hammond is Weltman's first hire with Orlando.
Gregg Allman of The Allman Brothers Band dies at age 69
His older brother Duane , a legendary guitar player, died in a motorcycle accident in 1971 at the age of just 24. Through the years, the group was responsible for hits like " Midnight Rider ", " Melissa " and "Whipping Post".
It is unlikely they will be overwhelmed by the challenges they face.
Weltman has a long track record of helping long-suffering franchises make major strides and become a perennial playoff power.
Weltman came to Milwaukee following one year as director of basketball administration in Detroit and five seasons as assistant general manager with the Denver Nuggets (2001-06). A veteran in NBA circles, he is relatively unknown to the casual basketball fan. Similar to Hammond's new operation in Orlando, it will be intriguing to see if Zanik continues to build Milwaukee's roster in the same mold in which Hammond did. Weltman said in the release. We wish John and his family nothing but the best in Orlando. Orlando owns the sixth pick in next month's NBA Draft and has about $14 million to spend in free agency in July.
Weltman, who will report to Magic president Alex Martins, was the Raptors' vice president of basketball operations prior to being promoted to general manager in September. "Jeff is a strategic thinker and strong leader, has great relationships in the industry and will bring a collaborative approach to our basketball operations leadership".
Instead of waiting, the Magic went after two accomplished executives known for team building.
