Hi
I'm in the process of upgrading CRM 2011 to 2013
Server upgrade went smoothly but when it comes to the organisation upgrade it ended up failing with the following sql exception from the log :
System.Reflection.TargetInvocationException: Exception has been thrown by the target of an invocation. --->
System.Data.SqlClient.SqlException:
The CREATE UNIQUE INDEX statement terminated because a duplicate key was found for the object name 'dbo.ActivityPointerBase'
and the index name 'fndx_Email_MessageId'.
The duplicate key value is (0, <20150309-17115912-2b8@RD-HO-WS4.RDTDMZ.LOCAL>, cc8f99fd-486e-4c39-aef7-7dd4d5fdbd0a).
When i checked the subject table in SQL it shows actual duplication for the same message id , not sure if this a common issue or it's more related to our own data
Appreciate any help
Thank you!
