Restore a Previous Version of a Server-Based Central Model

When using server-based worksharing, you can restore an earlier version of a central model.

Use either of the following workflows.

Note: In each of these cases, rolling back the central model will cause users' local copies of the model to sync with central.

To roll back a local copy of a model and promote it to function as a new central model

1. Identify a workstation with a local copy of the central model you wish to roll back.
2. Locate the backup folder for the central model, and copy this folder to another location.

   This step ensures that the Restore Backup process does not attempt to access the corrupt model stored in the original location.

3. Start Revit.
4. Click Collaborate tabManage Models panel (Restore Backup).
5. In the Browse for Folder dialog, navigate to the copy of the backup folder for the central model (created in step 2), and click Open.

   A dialog opens, showing the most recent versions of the RVT file.

6. Select the file version whose date and time correspond most closely to the period you wish to roll back to and click Save As to save this older version as a new model.
7. Open and detach this new model and save it to Revit Server as a new central model.
8. Direct users to create local copies of this new central model and resume their work.
9. Optional: Back up the old copy of the model and delete it from the server.

To restore a copy of the central model from your backup

1. Notify users that the model will be rolled back and that activity in the model must be halted.
2. Launch Radmin and lock the model you wish to roll back to block user activity.
3. Optional: Back up the model.
4. Delete the model.
5. Verify that the model's cache has been deleted on each local server.
6. Restore an older, archived model to the server:
   1. If the model was archived as an RVT file, open the RVT file in Revit and save it to Revit Server as a new central model.
   2. If the model was archived as a folder from the Revit Server Projects directory, simply copy that folder back into the Revit Server Projects directory.
7. Direct users to create local copies of this new central model and resume their work.
