# Manual object evolution

Manual object evolution is a process in several stages, where the user selects the objects that can be evolved, based on the file formats available to evolve into. Said selection does not necessarily have to respond to real evolution needs due to format expiration or obsolescence (which would have already been taken care of by the automatic format evolution).   &#x20;

Source format and destination format have to be selected, which will cause to load those evolvers available in the _Evolvers_ section (for that source format – destination format pair) and in a section for the selection of objects called _Object evolution_.

In the _Object evolution_ section, there is a drop down where the areas can be selected separately or by selecting the item _All the areas_. Once selected, all the objects available for evolution will be loaded. After marking the desired ones, the button ‘Evolve selected’ has to be clicked on.

A message warning about the start of the evolution of the selected objects will be shown. From that point on, the process can be followed from the main screen of ‘Evolution jobs’, where all the jobs and their status will be listed.

**Note**: LIBSAFE will create an evolution-type ingestion job for every object the user wishes to evolve.
