Data migration
There is a difference between data migration and data integration activities. Data migration is a project by means of which data will be moved or copied from one environment to another, and removed or decommissioned in the source. During the migration (which can take place over months or even years), data can flow in multiple directions, and there may be multiple migrations taking place simultaneously. The ETL (extract, transform, load) actions will be necessary, although the means of achieving these may not be those traditionally associated with the ETL acronym.
Format shifting
Format shifting is the conversion of media files into different file format or Data compression (video coding format and audio coding format). This may be required to play the media on different devices, for example when converting or ripping audio files on CDs into digital formats such as MP3. Other media shifting processes include time shifting (also known as place shifting), a process whereby a radio or television broadcast is recorded to disk storage and played back at a different time, and space shifting where media is stored on one device and can be accessed from another place through another device which is normally located at another location.
