Considerations
Only the downstream company account can initiate a connection with an upstream account's project.
An upstream project can support connections with multiple downstream projects. For example, multiple subcontractor companies (downstream) projects can connect to a single general contractor (upstream) project and receive drawings.
A downstream project can only connect to one upstream project.
'Admins' of the Connection Manager tool at either the upstream or downstream project can disconnect projects at any time.
Once a downstream project disconnects from an upstream project, it is not able to reconnect to that same upstream project or establish new connections with any other upstream projects. This is a one-to-one termination that doesn't affect other downstream accounts connected to the project.
