Abstract

An example computer-implemented method to translate a namespace includes receiving a first synchronization request associated with a first content item. This first synchronization request can include a first content item path and come from a client device. The example method can then include determining that a portion of the first content item path matches an entry path in an entry in a namespace mount table. The entry can include a second namespace. The example method can then include modifying the first synchronization request by removing the portion of the first content item path and including the second namespace in the first synchronization request. The example method can then include sending the first synchronization request to a content management system.

11. The non-transitory computer-readable medium of claim 10, wherein the entry path includes the old collection name, wherein replacing the portion of the entry path that matches the old collection path with the new collection path comprises replacing the old collection name in the entry path with the new collection name.

12. The non-transitory computer-readable medium of claim 8, wherein the computer executable instructions further cause the computer to:
