Cast Iron Central Heating Pipe Question

[WHPES]

A regular customer - a hotel I look after has a 1950s heating circuit which is in 4" spigoted cast iron lengths. They want to redesign a function room which involves altering part of it. Whats the best means of joining cast iron to steel pipe? Not had to do it before quite like this.
