i'm running moss 2007 RTM ver., with both application & db on a single server.
Current setup already has more than 1000 users with approx 200 concurrent user.
We also have quite a few workflow application running on this & is a kind of
central repository for key business critical documents. Going forward we have
planned to installed SP1, i know we are late in doing this .....but my worry is
that; will all the customizations done earlier continue to work .....or will i
face problem's after installing SP1, for the customization done in RTM....Also
would like to mention we had earlier migrated from sharepoint 2003 to moss 2007
on the same server.. everything so far is working fine with end user benefiting
from the applications we have rolled out..
