Overview
You can open only one system project at a time in an instance of the Topology Manager.
Data of objects that you edit by using the Topology Manager is automatically persisted in the Control Expert repository.
Hotfix Availability
To open, a system project requires the hotfixes that were installed on the computer at the time of its creation plus, any additional hotfixes that are installed on the computer on which you open it.
Thereafter, you can reopen the system project only on computers on which all these hotfixes are installed; otherwise, a dialog box opens, which indicates the hotfixes that are missing.
You need to install these hotfixes to be able to open the system project.

Closing a System Project
You cannot close a system project unless you:
Open another system project in the same Topology Manager instance.
Connect to another system server.
Close Control Expert.
You need to confirm closing the system project that is open.
Recovered System Projects
In case the software is not able to read the metadata of existing system projects (for example, their identifier) from the Control Expert repository, the next time the system server is started, the system projects are recovered and remain functional. Only their original properties are lost and the system project identifier is replaced with Recovered_ID where ID is a randomly generated string to maintain identifier uniqueness.
