SYMPTOM:
A user would like to restore the information for many project sources on a computer but does not want to manually re-create them through Developer or Project Source Manager.
CAUSE:
Project source information is stored in the registry:
HKEY_LOCAL_MACHINE\SOFTWARE\Wow6432Node\MicroStrategy\Data Sources
HKEY_LOCAL_MACHINE\SOFTWARE\Wow6432Node\MicroStrategy\Data Sources.

As long as all the DSNs that existed on the source exist on the destination with the same names the entire environment will be identical to the source machine.
NOTE: Users attempting this process should be aware that the CastorServer Data Source entry is the information used by the Intelligence Server to connect to the metadata on startup. If this information is copied from another machine, the DSN and other information for connecting to the metadata should be the same on the target machine, otherwise the Intelligence Server may be unable to start after copying the Data Sources.
