An error occurs when trying to upgrade an existing parcel fabric after upgrading the geodatabase to 10.1. The same error is encountered when using either the Upgrade Dataset tool or the Update Parcel Fabric tool:"ERROR 000100: The dataset %s cannot be versioned. Failed to execute (UpgradeParcelFabric).""ERROR 000100: The dataset %s cannot be versioned. Failed to execute (UpgradeDataset)."
The parcel fabric must be unregistered as versioned to be upgraded.
To upgrade the parcel fabric the geodatabase must first be upgraded to the current version/patch level of the ArcGIS client.
The Upgrade Parcel Fabric tool was deprecated at version 10.1. This functionality has been replaced by the Upgrade Dataset tool that upgrades the schema of a mosaic dataset, network dataset or parcel fabric to the current ArcGIS release.
