Proxima

If all your external files have been collected in the project's MediaFiles folder, the only thing you need to do when transferring a project to another server is make sure that you copy or move the full project folder (containing the MediaFiles folder and the .pxm file). use the export and import features located in the web interface of Proxima to do it.

In the event that a media file goes missing, you'll get this window when loading the project:

This window gives you the possibility to locate the missing files by giving it their new paths (make sure to collect & save the files afterward!) If you skip this window, you also have the possibility to locate each file from its associated module in the software (in the Sources panel for Medias, the Properties panel for player and group shaders, etc).

Even if you don't have the files at hand, you can edit other parts of your project and save safely, missing files information will still be kept in the backup and you can locate them anytime you want in a later session. 

Once a file has been located, it recovers all its saved properties in the project (attached player, parameters, controls assignments, etc).

Note: missing files can be deleted manually from their associated module in the software.
