.. _Modify_ReplaceNamespace:

Modify > Replace Namespace
""""""""""""""""""""""""""

This action opens a dialog that can be used to replace a selected namespace.
This can be for example used to migrate from one version of an asset collection to another.

All triples that use this namespace will be substituted, including those in selected other asset collections.
 
As a result this operation may take a long time to complete and directly modifies the
production copies, bypassing the change history.
Also the prefix declaration can be updated.

.. caution::
   This is an expert-level operation that cannot be undone and should be used with care.
