AX Upgrade Problem in Database Synchronization (duplicate key was found for the object name)

Hi All,

I have a problem durring the AX 2009 upgrade, I upgraded successfully Ax 3.0 SP5 database to Ax 2009 database, but in Ax 2009 upgrade checklist (Database Synchronization) step. I got this error:

"Object Server 01: The database reported (session 3 (Admin)): [Microsoft][SQL Native Client][SQL Server]The CREATE UNIQUE INDEX statement terminated because a
duplicate key was found for the object name ‘dbo.LEDGERJOURNALNAME’ and the index name
‘I_210JOURNALNAMEIDX’. The duplicate key value is (A34, A34-Intern)… The SQL statement was: "“ALTER TABLE LEDGERJOURNALNAME ADD CONSTRAINT I_210JOURNALNAMEIDX PRIMARY KEY CLUSTERED (DATAAREAID,JOURNALNAME) “””

Could some one helps please on how to resolve this error?.

Thanks & Regards,

Hani
