TARGET was initially developed to
Although TARGET has proved a success, two disadvantages have become increasingly apparent over time: first, the decentralised technical structure, and second, a lack of consistency with regard to technology and services. It became clear that the system would not be able to meet future demands in terms of efficiency, costs and stability.
With the introduction of TARGET2, the Eurosystem essentially provides
The Eurosystem opted for a phased migration approach, ie in the form of a number of "country windows". In line with this, the central banks, together with their respective national banking communities, were migrated from TARGET to TARGET2 in three groups. This migration process lasted a total of six months. During this period, TARGET2 and the TARGET components of countries that have not yet migrated were operated in parallel.
Germany migrated in the first country window (19 November 2007) together with Austria, Cyprus, Latvia, Lithuania, Luxembourg, Malta and Slovenia. Cyprus, Latvia, Lithuania and Malta had not previously participated in TARGET. Belgium, Finland, France, Ireland, the Netherlands, Portugal and Spain migrated in the second country window (18 February 2008).
In mid-May 2008, the TARGET system was completely replaced by TARGET2. Great Britain decided not to participate in TARGET2. All of the other remaining TARGET countries (Denmark, Estonia, Greece, Italy and Poland), as well as the ECB, migrated to TARGET2 on 19 May 2008.
In January 2009 and February 2010 Slowakia as well as Bulgaria joined TARGET2.
