You are unable to complete the Registration Wizard post K2 Cloud Update 8 upgrade.


During the Update 7 upgrade, all provider info was transferred from the old Badger schema to the new SyncEngine schema. Badger schema only allowed 50 characters for the Provider instance name and therefore truncated the name after 50 characters. This data was transferred to the SyncEngine schema in a truncated state. When running the registration wizard Provider Instances are queried based on the full name from Micro Service (Storage) and due to the fact that the name of the provider is truncated in the SyncEngine.ProviderInstance table, no match is found, and the error appears.

This is a legacy issue. To fix it the Name of the provider instance needs to be updated in the SyncEngine.ProviderInstance table and the Registration Wizard needs to be re-run.

Additional Script to help find the issue
The following Script will help find the possible Group Providers in this state, output will have the GroupProviders that doesn’t have a match in the SyncEngine.ProviderInstance table.

Ignore the Providers with Asterisk name (*)
Select * from [HostServer].[GroupProvider] where [Name] not in (Select [Name] from [SyncEngine].[ProviderInstance])

Note the Provider name that is returned and Query the SyncEngine.ProviderInstance table to find it.

Select * from [SyncEngine].[ProviderInstance] where [Name] like N’PROVIDERNAME BUT LESS THAN 50 CHARACTERS%’

Note the provider name from the SyncEngine.ProviderInstance table and update the record.

Update [SyncEngine].[ProviderInstance]
Set [Name] = 'Provider name from GroupProviderTable'
Where [Name] = 'ProviderName that is truncated from the ProviderInstance table'
