I've got a mixed netware network with 4.2, 5.0 and 5.1. I want to upgrade
to the Netware/Linux solution and would like to do the following, does
anyone see a problem.

Install the OES into a new tree IP Only (the old tree is IPX only)
Test, test, test.
Move the files over slowly, maybe one server at a time. At the same time
configure the clients for multiple tree login (possible?)

If multiple tree login isn't possible is bindery login on one tree and nds
login on another possible?

If not how does one go about doing this. The current tree is basically
healthly but I want to start fresh without any gremlins, but I also don't
want to just rip out the old over a weekend.

Any suggestions?
