SYMPTOM:
In the Strategy Project Mover Wizard of Strategy Enterprise Manager 9.x, when users are presented with the selection to specify a project source name that will be used to reference the Metadata either in 2-tier mode or 3-tier mode, the option to 'Create Project Source Name for Strategy Intelligence Server (3-tier)' is grayed out as shown below:

CAUSE:
This is an expected behavior if the Metadata is pointing to a Metadata other than where the Strategy Intelligence server is directed.
ACTION:
To have the option to 'Create Project Source Name for Strategy Intelligence Server (3-tier)' enabled, the Metadata should be pointing to the same Metadata to which the Strategy Intelligence Server is pointing.
