Currently running eDirectory 8.6.2 on NW6SP4 server. Want to install new
NW6.5 server into the tree and move data to new server.

Should I upgrade eDir on the NW6 server to 8.7.3 first or doesn't it matter?
If so, what is the easiest way to upgrade eDir and minimize downtime. We
are basically a 24/7 operation. Thank you.
