Abstract: Methods and systems for datacenter migrations are disclosed. A method includes: virtualizing, by a computing device, servers in a source environment; installing, by the computing device, an isolation firewall to isolate a target environment from the source environment; installing, by the computing device, shared services in the target environment; installing, by the computing device, monitoring and management tools in the virtualized servers in the source environment; replicating, by the computing device, between the source environment and the target environment; and cutting over, by the computing device, from the source environment to the target environment by switching a route advertisement from the source datacenter to the target datacenter.

Abstract: A method and associated systems for using complexity probability to plan a physical datacenter relocation. One or more processors receive descriptions of each entity to be relocated, each of which is identified by a classification and by a tier that is associated with a level of complexity. Normalized random numbers are generated for each classification/tier combination and are each associated with a relocation scenario in which random complexity has a distinct amount of effect on the duration of time needed to relocate entities of the corresponding classification and tier. These numbers are then used to identify probable relocation times, each associated with one scenario, one classification, and one amount of complexity effect. These probable relocation times are then organized by classification so as to identify complexity-compensated probabilities that relocating all entities of a particular classification will require a specific duration of time.
