Embodiments of the present invention relate to 'migration points' and an associated method and calculation tool. In general, a migration point is a number that represents an evaluation of the size and complexity of performing a migration, port, or refresh of an application from a legacy platform to a new target platform. When migration points are applied to applications across a portfolio, the migration points provide a relative measurement of the size and complexity necessary to perform the migration. Additionally, this measurement can be used to make a determination in calculating migration productivity (i.e., migration points divided by person-months, similar to how software productivity utilizes function points). In a typical embodiment, the migration point total is based on a set of qualitative migration points and a set of quantitative migration points, which are based on various technical aspects of the application, operating system, and hardware involved with the migration process.

Calculating migration points for application migration

A computer-implemented method and program product for estimating cost and/or time requirements for migrating an application from one platform to another. The method includes receiving identifications for tasks, receiving at least one assessment type selected for estimating cost and/or time requirement for migration, where the assessment type delineates a degree of accuracy for estimating the cost and/or time requirement for migration, correlating base costs and/or time requirements to the tasks identified, receiving identifications of attributes that affect base costs and/or time requirements, correlating cost and/or time factors to the tasks, a respective cost factor and/or time factor indicating an amount by which an attribute affects the respective base cost and/or time requirement for a task, and estimating cost and/or time requirements for each task, by applying the respective cost and/or time factors for each task to the respective base cost and/or base time requirements for each task.

Method and program product for costing and planning the re-hosting of computer-based applications

The present invention describes a method and system for preparing a migration and consolidation of at least one source application to be migrated to or consolidated in at least one heterogeneous server device. A computing system selects at least one prospective target platform component based on an evaluation of at least one source platform component, a requirement of the at least one source application, and a compatibility and an affinity of the at least one prospective target platform component. The computing system collects first metadata of the at least one source platform component and the at least one prospective target platform component. The computing system collects second metadata associated with the migration and consolidation. The computing system groups the first metadata and the second metadata into a RFM (Request For Migration). The computing system prepares and configures a final target platform in accordance with the RFM.

Assisting server migration

An exemplary method (which can be computer implemented) for enhancing migration of software applications from a source system environment to a destination system environment includes the steps of translating needs into requirements for the destination system, capturing deployment and configuration of the software applications in the source system environment and the destination system environment in a centralized model, analyzing dependencies between the systems in the source and destination systems to construct a mapping between the requirements and elements of the model, and generating enhanced migration rules, based, at least in part, on the mapping.

Method for optimizing migration of software applications to address needs

A method (which can be computer implemented) for addressing errors during migration of software applications includes the step of obtaining access to a data repository, which includes a listing of migration decisions and a listing of dependencies associated with the migration decisions. The method further includes the steps of obtaining an indication of a migration error, tracing the migration error to at least a first one of the migration decisions in the data repository, and employing the listing of dependencies to identify at least a second one of the migration decisions, depending on the at least first one of the migration decisions identified in the tracing step, which is impacted by the migration error. Techniques for populating the data repository are also provided.

Method for enabling traceability and recovery from errors during migration of software applications

A computer determines a first plurality of servers which have a lease set to expire within a predetermined period or current or projected peak utilization greater than a predetermined percentage of their capacity. The computer determines a second plurality of servers which have sufficient lease term and excess capacity. The computer determines and records which servers of the first plurality to consolidate on servers of the second plurality based on sufficient capacity, match of application(s) and projected life span of the application(s) of the second plurality, and determines a schedule for retiring the servers of the first plurality with the applications having insufficient projected lifespan, and estimates cost savings for the consolidation.'
