The story was originally reported by MLB.com Rangers beat writer T.R. Sullivan.
Servais, 44, had served as the Rangers' senior director of player development––or farm director––since being hired by the club in 2005. The former 11-year major league catcher helped the Rangers build and maintain what has been consistently regarded as one of baseball's top minor league systems over the last six seasons.
Servais will report to Dipoto in his new job, and he will continue to oversee the minor leagues. His official title is "Assistant General Manager, Scouting and Player Development."
"I would like to thank the Texas Rangers for the opportunity they gave me," Servais said in an Angels press release. "They have some phenomenal baseball people from which I have learned a tremendous amount. I'm thrilled to join yet another top organization in the Angels, owner Arte Moreno, president John Carpino and general manager Jerry Dipoto.
"We will hit the ground running in the scouting and player development program to ensure the success of the Angels now and for years to come. It will be our goal to always have a championship-caliber team for our fans."
According to FOXSportsSouthwest.com's Anthony Andro, Rangers' general manager Jon Daniels "won't speculate on a Servais replacement" at this time.
Servais not only oversaw the Texas farm system, but he also assisted in both coaching and personnel decisions at all levels of the organization.
If the Rangers choose an in-house replacement for Servais as farm director, potential candidates could include current assistant director of player development Jake Krug or minor league field coordinator Mike Micucci. Krug, who joined the organization in 2003 as an intern in the scouting department, was the Rangers' east coast crosschecker prior to taking his current position. Micucci managed at short-season Spokane, Single-A Clinton, and Double-A Frisco before becoming the field coordinator in 2010.
