Amendment: Migration from SIS 1+ to SIS II (Decision 2008/839/JHA)

This procedure concerns the transition from the older Schengen Information System (SIS 1+) to its upgraded version, SIS II. This upgrade aims to enhance the system's capabilities for managing information related to border control and security within the Schengen area.

The changes affect border management authorities and law enforcement agencies that rely on the SIS for cross-border cooperation. It ensures continued seamless operation and improved data sharing for maintaining security and facilitating free movement.
