Go to the <12 Hive>\LOGS folder and check the log files. The migration log file should tell you what about the sites and Features need to be cleaned up. It's usually Features that you need to deactivate on the site collection before migration, that causes a problem. These are almost always custom Features. In addition, it seems you may have an orphaned site somewhere. It needs to be identified and either restored or deleted. I trust that answers your question... Thanks C http://www.cjvandyk.com/blog

ok, how to remove the feature or site that i no longer need ? thanks man./* Infrastructure Support Engineer */

You can deactivate feature in those pages depending on the scope of your feature(http://weblogs.asp.net/soever/archive/2007/05/03/sharepoint-features-elements-scope-and-other-info.aspx): Site Settings-> Site Features, Site Settings->Site Collection Features Central Administration->Operation->Manage Farm Feature Central Administration->Application Management->Manage Web Application Feature You can retract solution in Central Administration->Operations->Solution Management.

here's the update about what I've done so far: I tried to remove it manually using STSADM.exe C:\>stsadm -o uninstallfeature -id bc59afa4-5412-4148-8a23-1e7e6d122d7f Failed to find the XML file at location '12\Template\Features\BatchSiteManagerLinks\feature.xml' C:\>stsadm -o uninstallfeature -id 20e9ecab-2d22-41eb-892d-933afc32793e Feature with Id '20e9ecab-2d22-41eb-892d-933afc32793e' is not installed in this farm. The feature was not uninstalled. but still no joy. I've got more than one of the missing item, see below, does these items need / must be cleaned first before migrating ?
