This article was created in response to a support issue logged with K2. The content may include typographical errors and may be revised at any time without notice. This article is not considered official documentation for K2 software and is provided "as is" with no warranties.


An error appears at the last part of database consolidation: Constraint, Proc, Index.

"Database consolidation was cancelled or failed. See log for more information."



The installer log generated by the tool shows the error "Could not re-encrypt."

It points to a particular entry in the [CustomUM].[User] table inside the K2SQLUM database where UserID=0 fails to get decrypted.

Troubleshooting Steps

Prior to running the consolidation tool, remove the entry on the table which fails to get decrypted:
DELETE FROM [K2SQLUM].[CustomUM].[User] WHERE [UserID] = 0

If this does not help, please ensure that the connection string (VariableValue) points to the SQL server instance where the single K2 database will be hosted:
SELECT [VariableToken], [VariableValue] FROM [K2HostServer].[HostServer].[Configuration]

Should there be a need to update a connection string, kindly log a K2 Support Ticket as direct manipulation of data stored inside the K2 database without the supervision of a K2 personnel could put you in an unsupported state.
