RDN Synchronization - Troubleshooting Migration

Symptom

Probable Cause

Solution

After you initiate the migration, the following error message appears:

"Data migration failed, see error logs. Migration of data to GDM model: End <timestamp>. Result: Fail – check software error logs for failure details."

Migration has failed on the local element.

Investigate the error logs on the failed element, resolve any issues, and then retry the migration from the failed element.

To retry the migration, click  the Remigrate Data Distribution button in the Shared Forms Configuration form.

At the end of the migration procedure, you enter the Migration Status maintenance command. The system response indicates that the migration is still in progress on a remote element.

Communication failure during the migration resulted in the loss of the migration event on the element.

Check for a pending data distribution update on the element where you initiated the migration. See Viewing Data Distribution Updates

Retry the pending update. Then, synchronize the form data to the newly migrated element.

When adding a new element to a migrated network, you receive either of the following error messages after you initiate the Start Sharing operation:

"Synchronization failed. You must migrate this node to the new data model before attempting to join the SDS network"

"Synchronization failed. The target for this operation must migrate to the new model first".

You attempted to add a non-migrated element to the migrated network.

Follow the procedure described in Adding an Element to the Migrated Network.

After migrating the network or cluster you are unable to import users from the Import Spreadsheet

You are attempting to use an old version of the Import Spreadsheet.

Download the latest version of the Import Spreadsheet for the migrated system. See Download an updated version of the Import/Export spreadsheet.
