I have a mixed Tree of Nw6.5 Sp3-Sp6. My servers that hold Root are at

first, so I always install a new Sp on a non-Root server. I have usually
done one with a replica to ensure schema propagation, but have
occasionally done the first Sp install on a server without a replica.

Has Sp7 changed any of that? Can I still do my first Sp install on a non-
replica server if I have too? I will try to do a server with a replica

I have read there are major issues with iPrint plugins again. Once
iManager 2.7 is installed, none of the iPrint plugins will work in
iManager 2.6?
