I have several Netware 6 SP3 servers with eDir 8.6.2

I am looking to introduce my first Netware 6.5 server into my tree as pre
migration server.

I relise I need to run NWDEPLOY before hand, no doubt it will highlight a
few issues, should I go one step ahead of NWDEPLOY and upgrade all the
servers to 8.7.3.?? and SP5 first???

Thanks in advance
