Surrey promoted Vikram Solanki to the position of coach, replacing Michael di Venuto.
Ex-scout from Surrey, Worcestershire and England, 44, was Di Venuto's assistant since 2018.
Australian Di Venuto & # 39; s departure was confirmed last month after a four-year period that included winning the Championship County title in 2018.
So far, there has been no cricket in the municipality because of the coronavirus, but games may be possible from August.
A club statement said Solanki "will take over immediately and work with the Surrey team as soon as professional players can return to group training".
He also has experience as a coach in the Indian Premier League and has served in the past as interim president and chief executive of the Professional Cricketers & # 39; Association, the players' union.
Solanki has also been president of the Federation of International Cricket Associations (FICA) since 2017.
"Now I am really excited to take over as coach. We have a very talented group of players at Surrey CCC and we look forward to competing in all formats – in any competition that can be held this summer and in the future," he told the club website.
Cricket director Alec Stewart added: "I am very lucky to be able to nominate someone who knows our organization and players from the inside out – but it has also expanded his coaching experience around the world in recent years.
"I have complete confidence and faith that Vikram will take on this new role and the associated challenges and responsibilities."
Although his international career was limited to limited matches, Solanki scored over 18,000 first-class races, including 34 centuries and the best of 270 for Worcestershire against Gloucestershire in 2008,
