? I must read that differently to you :-) ?

current realservers : A,B,C
servers to swap into the system instead  D,E,F

* Add servers D,E,F into the system all with fairly high weights (perhaps
  ramping the weights up slowly so as not to hit them too hard:-)
* Change the weights of servers A,B,C to 0.
* All new traffic should now go to D,E,F
* When the number of connections through A,B,C reaches 0, remove them from
  the service. This can take time I know but...

Has the required effect.
