Revit: Can’t create new local model after moving central model to a new server

Issue:

After moving the Revit central model to a new location or renaming the server, the Create New Local checkbox is grayed out and a message appears “The central model has been copied or moved”.

Causes:

When a Revit model is moved to a new location, it must be resaved as a central model.

Solution:

To save as a new central model:

1. Open the Revit model.
2. Select File > Save As > Project.
3. In the Save As dialog, select the Options button.
4. In the File Save Options dialog, check if “Make this a Central Model after save” is enabled.
5. Select OK.
6. Select Save.
