In the next couple of weeks, I'll be upgrading our master of Root to OES.

I've restored the Master of Root onto a test server in the lab to
perform the upgrade.
When I upgrade the master of Root (NW6.0 Sp5 eDir 8.7.3) to OES, all the
web services break.
The server is configured as follows: - iPrint, Remote Manager - Novonyx Web servers - NetStorage, WebAccess - iFolder

I'm aware that OES migrates all Novonyx services to Apache2, but the OES
upgrade seems to move all the web services to the address
and disregards the .22 and .23 addresses...

Is there any way to migrate the web services to OES without changing
their IP addresses?

Thanks for your help.
