 When the Dodgers and Giants moved to California from New York, they played in Los Angeles Memorial Coliseum and Seals Stadium respectively while Dodger Stadium and Candlestick Park were being built.The other case is when, rather than building a new park, the city renovates an existing minor league or college facility, expanding it to fit a major league team.These converted ballparks are different from football stadia that were converted to facilitate baseball in that converted ballparks were originally built to be baseball only, albeit for a non-major league level.
