A system and method for information technology (IT) migration includes determining a relationship among objects to be migrated such that the relationship includes a set of objects having at least one of a common feature or dependency between the objects in the set. The objects are grouped into a plurality of migration waves such that cross-wave relationships are minimized among the plurality of migration waves. The objects are migrated wave by wave.

System and method for object migration using waves

Methods and systems for finding a migration target include building a constrained, layered graph from a catalog of possible configuration combinations and a distance function for each layer in the graph; and determining an available path through the graph, said path having a minimum overall distance from a source instance, by performing an optimized search that selectively evaluates available paths through the graph based on cumulative distances of paths through the graph from the source instance.

Efficient configuration combination selection in migration

Access is obtained to raw historic information technology migration data, which data is transformed in accordance with a classification scheme to obtain classified key historic information technology migration data. A statistical model with conditional distributions of the key historic information technology migration data is built. Prior to a new information technology migration project, access is obtained to incomplete data characterizing the new information technology migration project. The statistical model is used to derive data missing from the incomplete data characterizing the new information technology migration project, to obtain derived data. At least one of a migration plan and an estimate for the new information technology migration project is created based on the incomplete data and the derived data.

Migration estimation with partial data

A method and system for discovering dependencies, configurations and utilizations among IT resources are disclosed. A discovery team writes a prediscovery script without requesting credentials and sends it to a system administrator (SA) who already has necessary credentials to execute the prediscovery script. Then, the SA reviews the prediscovery script and executes the prediscovery script on a target server. While or after executing the prediscovery script, the target server generates a result of an execution of the prediscovery script and provides the result to an analysis system. The analysis system analyzes and parses the result and generates a user-friendly data (e.g., graph or spreadsheet) that represents the result. Then, the analysis system provides the user-friendly data to the discovery team. The analysis system does not require credentials and does not directly communicate with the target server except receiving the result of the executed prediscovery script from the target server.
