Running nw6sp4 here, & all is running good. <knocks on wood>

Been told by a couple different people in the support forums I should
be at sp5 & nss5c at least, so looking into that.

I have 12 Netware boxes here, and I was wondering if it's possible
(adviseable) to run an environment of sp4 & sp5 for a day or 2 until I
could get all servers updated.
