A & B Cluster Difference

Hi All,

What is the major difference between A Cluster and B Cluster?

If I implement SAP Business One 2005 B in Europe or if I implement 2005 A in China, India, Singapore etc, what are the issues that I can foresee?

Alternatively, is it possible to generate 2005B License File if I purchase 2005A and vice versa?

Thanks in advance
