Fixing embedded richtext links in copied related assets

Machine logic for: receiving data set (for example, a website) that includes a plurality of links, with the links respectively identifying logical locations of data stored on a set of server computer(s); and making a deep copy of the servable data set on the set of server computer(s), with the deep copying including: copying each link of the plurality of links of the servable data set from a respective source logical location to a respective target location, and adding each copied link of the plurality of links as a record in a mapping table. The mapping table can help to automatically update/replace links wherever they are found in related system artifacts. If the resolution can't be automatically determined then the system suggests possible target links for manual inspection/updates based on the likelihood of correctness, artifact types, and user roles.
