We currently have 4 trees running NW6 w/SP4.

Over the last few months, we have just finished a project to connect all
of our building via fiber. Now, we are considering moving to one tree and
upgrade to NW6.5.


Is it better to upgrade each of the trees to NW6.5 first and then merge
the trees?


Is it better to merge the trees and then upgrade all servers to NW6.5?

We also will have to look into design considerations for SLP services and
reconfigure some DHCP options.

Any thoughts appreciated.
