Embodiments of the present invention address deficiencies of the art in respect to application migration and provide a novel and non-obvious method, system and computer program product for application migration through migratable units. In one embodiment, an application migration method can include decomposing an application migration into a plurality of migratable units (MUs). The MUs can be prioritized for migration to a target platform. Thereafter, each of the MUs can be migrated in an order defined by the prioritization. Finally, a stateful wizard can be provided which can reduce the complexity of the migration by providing a dashboard to the migration process.

Migratable unit based application migration

A messaging system for masking addresses from sending processes. The messaging system maintains a message service profile and a service-address profile. The messaging system accesses recipient data. Sending processes are able to send messages to the messaging system in a form such that each message has an message type and list of recipients. The messaging system is able to determine which of a set of sending services is to be used to send the message, based on the message-service profile. The service-address profile stores information about where in the structure of recipient data the appropriate address for the selected service is located. The addresses corresponding to the named recipients, for the services determined by the messaging system, can be retrieved by from recipient data. The message system can then provide the recipient address to the appropriate sending services to send the message.

Recipient address masking in computer communications

A Web-based computer system is provided with software for processing of inbound messages originating from a back office system. The computer system or web-based application may be operated to maintain the consistency of the information on both systems. A method of operating the computer system and application is also provided. The method, system and application accommodate use of multiple inbound queue server processes, multiple ports for sending messages from the back office system and multi-threaded processing in the web-based application system. The various inbound messages received by the web-based application system are processed in proper time sequence. Every document created by the back office system is identified with a unique primary key. The primary key identifies the type of document and the document number corresponding to the particular document. The document and a timestamp identifying the date and time of the document's creations are stored in the back office database. The web-based application system receives an inbound message including the document information from the back office system. Upon receipt, the web based application system searches a database listing primary key information of earlier received messages and compares the primary key information of the inbound message. If the primary key of the inbound message matches a stored primary key entry, the timestamps of the two messages are compared. The message having the later timestamp is identified as the most current version and is recorded in the web-based application database.
