Parallel adoption is a method for transferring between a previous (IT) system to a target (IT) system in an organization.
 In order to reduce risk, the old and new system run simultaneously for some period of time after which, if the criteria for the new system are met, the old system is disabled.
 The process requires careful planning and control and a significant investment in labor hours.
Michael Tellinger, is a South African scientist, author, researcher, explorer and humanitarian, whose work touches the areas of science, spirituality, religion, mythology, sound, resonance, the nature of our reality and consciousness.
 More information can be found on his website http://michaeltellinger.com/ Tellinger is the author of several books and founder of the UBUNTU LIBERATION MOVEMENT of higher consciousness and the UBUNTU Party in South Africa.
 The UBUNTU Movement https://ubuntuplanet.org/ and its philosophy has supporters in over 140 countries and promotes the establishment of a new social structure to release humanity from the stranglehold of money and capitalism.
 Tellinger calls the new system Contributionism.
 The philosophy is captured in his 2014 book called UBUNTU Contributionism - A Blueprint For Human Prosperity.
 In 2008, Michael Tellinger exposed a vast vanished civlisation in southern Africa, that has left behind the largest continuous cluster of stone ruins found anywhere on Earth to date.
 He claims that they left behind mysterious tools and artefacts, which indicate that this ancient civilisation had an advanced knowledge of sound and resonance and that they used sound as a source of energy.
 Detailed information and images are contained in his books Adam's Calendar and Temples of the African Gods and in numerous online lectures.
 In his 2005 book Slave Species of god, Tellinger casts an alternative spin on human origins by combining diverse areas of research, claiming that humanity did not evolve out of apes, but were cloned by a group of beings that are collectively called the Anuna gods (ANUNNAKI) in the Sumerian clay tablets.
 In his numerous online lectures and videos, Tellinger shows how sound and resonance are the source of creation and how all things, seen and unseen, manifest into our reality and this dimension from the so-called void or zero-point or morphogenetic field.
Big bang adoption or direct changeover is the adoption type of the instant changeover, when everybody associated with the new system moves to the fully functioning new system on a given date.
 This is the simplest method of changeover.
Administrative divisions of Ukraine in 1918 was inherited from the Russian Empire and was based on the system of gubernias (provinces) divided into povits (counties) and volosts (districts).
 New administrative reform was adopted by the Central Council of Ukraine on March 6, 1918 which saw restructuring the subdivision of Ukraine based on a new system of regions (zemli) and abolishing system of gubernias and povits.
 Implementation of the new system was never fully realized and after the Skoropadsky's coup-d'etat on April 29, 1918 was abandoned.
The Year XI system (French:"Système An XI", after of the 11th year of the French Republic, i.e. 1803) was a French artillery system developed during the rule of Napoleon.
 The Year XI system was original in that it brought various improvements to the highly successful Gribeauval system, on which many successes of the Napoleonic Wars relied.
 It especially consisted in streamlining the existing Gribeauval designs.
 The main proponent of the new system was General Marmont.
 It was superseded by the Valée system.
A New System of Domestic Cookery, first published in 1806 by Maria Eliza Rundell (1745 – 16 December 1828), was the most popular English cookbook of the first half of the nineteenth century; it is often referred to simply as "Mrs Rundell", but its full title is "A New System of Domestic Cookery: Formed Upon Principles of Economy; and Adapted to the Use of Private Families".
John Dalton FRS ( ; 6 September 1766 – 27 July 1844) was an English chemist, physicist, and meteorologist.
 He is best known for proposing the modern atomic theory and for his research into colour blindness, sometimes referred to as Daltonism in his honour.
The Rorschach Performance Assessment System (R-PAS) is a scoring method to be used with the Rorschach inkblot test.
 This system is being developed by several members of the Rorschach Research Council, a group established by John Exner to advance the research on the Comprehensive System, the most widely used scoring system for the Rorschach.
 Following Exner's death, the council admitted that the current Comprehensive System scoring was in need of revision.
 But rather than updating the existing system, a new system was established.
 The introduction of a new system, as opposed to modification of the existing system, has caused some controversy.
Administrative divisions of Ukraine in 1918–1925 was inherited from the Russian Empire and was based on the system of gubernias (provinces) divided into povits (counties) and volosts.
 New administrative reform was adopted by the Central Council of Ukraine on March 4, 1918, which saw restructuring the subdivision of Ukraine based on a new system of lands and abolishing system of gubernias and povits.
 Implementation of the new system was never fully realized and after the Skoropadsky's coup-d'etat on April 29, 1918, was abandoned.
In chemistry, the law of multiple proportions is one of the basic laws of stoichiometry used to establish the atomic theory, alongside the law of conservation of mass (matter) and the law of definite proportions.
 It is sometimes called Dalton's Law after its discoverer, the British chemist John Dalton, who published it in the first part of the first volume of his "New System of Chemical Philosophy" (1803).
 Here is the statement of the law:
