[HCN] Merging two MDW3 databases?

[Peter Machell]

  Having liberated a doctor from Windows on desktops at one of his new  
sites (by using terminal services back to a server at another site) he  
now has asked me to work through and centralise existing sites.

Last time I asked support it was only possible for HCN to merge two  
MDW3 databases. Has anyone had this done, what was the timeframe and  
how was the result?

regards,
Peter.
