I am deploying IDM 3 (Bundled edition) in my test environment to prepare
for the actual deploy in the live environment. This involves upgrading
from dirXML 1.1a and password sync 1.0. I have created a second tree for
the ID Vault, and installed the Metadirectory Engine on it. But the
original DirXML engine is running on the user's tree. My assumption was
that the users tree would then simply become a connected system to the
Vault. So do I need the Metadirectory engine running in both trees? How
does IDM know which tree is the Vault, and does it matter?
