1. A method comprising: obtaining data characterizing a source computing environment having at least one hardware resource and at least one workload; obtaining a specification of a target computing environment to which said at least one workload is to be migrated in a migration; based on said data characterizing said source computing environment and said specification of said target computing environment, categorizing said migration into one of a plurality of categories; and specifying said migration in accordance with a migration technique selected based on said categorizing step, wherein said categorizing of said migration comprises: determining whether an operating system version upgrade is required; determining whether at least one of a middleware upgrade and an application upgrade is required; determining whether an internet protocol address change is required, categorizing said migration into a first category if said operating system version upgrade is not required, said at least one of a middleware upgrade and an application upgrade is not required, and said internet protocol address change is not required; categorizing said migration into a second category if said operating system version upgrade is not required, said at least one of a middleware upgrade and an application upgrade is not required, and said internet protocol address change is required; if said operating system version upgrade is not required, and said at least one of a middleware upgrade and an application upgrade is required, determining whether a new server build is required; if said operating system version upgrade is not required, and said at least one of a middleware upgrade and an application upgrade is required, and said new server build is not required, categorizing said migration into a third category; and if at least one of: said operating system version upgrade is not required, and said at least one of a middleware upgrade and an application upgrade is required, and said new server build is required; and said operating system version upgrade is required; categorizing said migration into a fourth category.
