The Flames went from Atlanta to Calgary, then the Thrashers want from Atlanta to Winnipeg.

From the WIKI:

The 1979 merger of the NHL and WHA was the culmination of several years of negotiations between the National Hockey League (NHL) and the World Hockey Association (WHA) that resulted in four WHA franchises, the Edmonton Oilers, New England Whalers, Quebec Nordiques, and Winnipeg Jets joining the NHL for the 1979–80 season.

Don’t forget that Hartford(New England) is now the Carolina Hurricanes!
