Abstract: According to some embodiments, systems and methods are provided, including a repository storing at least an Application Programming Interface (API) mapping table; a memory storing processor-executable program code; and a processing unit to execute the processor-executable program code to: receive an input of one or more legacy API identification elements for a legacy API; determine whether the received legacy API identification elements correspond to a standard legacy API; in a case the received legacy API identification elements do correspond to a standard legacy API, determine whether a corresponding updated API is available; in a case the corresponding updated API is available, determine whether the legacy API includes at least one extension; and in a case the legacy API does include at least one extension, generate an updated corresponding API extension, and transmit the corresponding updated API and the updated corresponding API extension to the user. Numerous other aspects are provided.

Abstract: Extensions to a source software application are migrated to a target. Template records are constructed containing corresponding sets of attributes for source and target applications. Analysis of a source extension yields source extension attributes. A matching template record is used to map the source extension attributes to corresponding target extension attributes. A proposal for a migrated target extension is formulated, simulated in a sandbox, and committed to the target application. Client interaction supports selection or approval of application versions, proposals, or simulation output. Template records, constructed without knowledge of specific extensions implemented on a particular application instance, are provided to the source application environment, enabling remaining migration operations to be performed locally in source and target environments, maintaining data privacy. Examples are provided for a front-end software application in a database environment.
