[logu_paps]

Having alfresco enterprise 6.2 with documents and planning for 7.2 upgrade.having a custom model with namespace prefix as "dc". While alfresco 7.2 bootstraps,getting an error - context initialisation failed org.alfresco.service.namespace.NamespaceException:Namespace prefix "dc" is already in use for URI http://pur1.org/dc/elements/1.1 so cànnot be registerd for uri.

Let me know any solution for this isse

Yes I think "dc" prefix is used by alfresco

Alfresco has a list of content model namespaces and prefix which should not be used attached link of alfresco docs (Refer topic : Out-of-the-box content models) , Also there are lot more other mentioned prefix and which might cause issue
