  Hello all,
  I need some advice regarding upgrading from CRM 4 to CRM 2011. Our customer has 3 intances of CRM 4 installed. They want to upgrade to CRM 2011 but have a small issue. They dont want to upgrade to 3 seperate instances of CRM 2011 bur rather want only 1 CRM 2011 instance with three business units. basically they want to combine the data from 3 CRM 4 instances into 1 CRM 2011 instance and only seperate the data based on business units.
  1) What would be the best way to achieve this?
  2) Do I need to upgrade one of the CRM 4 instance to CRM 2011 instance and then import the data from the other two CRM 4 instances into this?
  3) Could you suggest me the best practices to do this?
  4) Do I need to take care of any aspects when doing this upgrade?
  Any helpful suggestions from you guys would be greatly appreciated.

  Thanks in advance,

  Nemath
