Hello...
Below you will find the methode for deleting the corrept packages from the manager..even if its the lateste version, cause in this case you are not allowed to delete it or even upload a new one...
This apllied to
12.1 RU5
Corrept packages
Externel databese SQL 2008
Befor acceccing to SQL Server, stop the SEPM services on your manager.
Connecte to SQL Management Studio
Run the Query : SELECT * FROM sem5.dbo.BINARY_FILE WHERE TYPE='ClientPackageFile'
Run the Query : DELETE FROM sem5.dbo.BINARY_FILE WHERE TYPE='ClientPackageFile'
Done....
Now you can acces to your manager, verifi that the packages are no more avlaible...
Now you can export the packages from SEPM folder....
This methode was given by a Symantec support technicien.
It was tested and it works,
I hope this may help...
Thanks :)
