METHOD AND SYSTEM FOR AUTOMATED SYSTEM MIGRATION
Methods, systems, and programs described herein can provide automated testing and migration from a first application instance to a second application instance with minimal impact on the operational system. A parallel testing environment is automatically established to allow for parallel processing of inputs and comparison of outputs.
1 . A method for migrating operations from a first application instance on a machine having at least one processor, storage, and a communication platform to a second application instance, comprising the steps of:
configuring the second application instance on a machine;
providing an input intended for the first application instance to the second application instance;
processing the input with the first application instance and processing the input with the second application instance;
generating a first output and a second output; and
comparing the first and second outputs.
2 . The method of claim 1 wherein the providing an input intended for the first application instance to the second application instance comprises:
duplicating the input from an input source intended for the first application instance and furnishing it to the second application instance.
3 . The method of claim 1 wherein the providing an input intended for the first application instance to the second application instance comprises:
linking the input from an input source intended for the first application instance to the second application instance.
4 . The method of claim 1 further comprising:
eliminating the first application instance based on the results of comparing the first and second outputs.
5 . The method of claim 4 wherein the eliminating is done automatically based on a trigger based on time, number of transactions, a measure of data, or a date certain.
6 . The method of claim 1 wherein the second application instance is setup automatically via the communications link.
7 . The method of claim 1 further comprising:
storing the generated first and second outputs.
8 . The method of claim 1 wherein the comparing of the first and second outputs are compared in real time.
9 . The method of claim 7 wherein the comparing occurs after storing of the first and second outputs
10 . A machine readable non-transitory and tangible medium having information recorded thereon for migrating a first application instance on a machine having at least one processor, storage, and a communication platform, to a second application instance to causes the machine to perform the following:
configuring the second application instance;
providing an input intended for the first application instance to the second application instance;
processing the input with the first application instance and processing the input with the second application instance;
generating a first output and a second output; and
comparing the first and second outputs.
11 . A system for automatically migrating from a first application instance to a second application instance comprising:
a first system for implementing a first application instance;
a second system for implementing a second application instance;
a data replicator for replicating the input from the first application instance;
a communications link for conveying the replicated inputs from the first application instance to the second application instance; and
an output comparator for comparing the output of the first application instance and the second application instance.
12 . The system of claim 11 wherein the first system and the second system are implemented on one system.
13 . The system of claim 11 where the second system comprises the second application instance, the data replicator, and the output comparator.
14 . The system of claim 11 wherein a portion of the first system is implemented in a cloud computing environment.
15 . The system of claim 11 wherein a portion of the second system is implemented in a cloud computing environment.
16 . The system of claim 11 wherein a portion of the first system and the second system are implemented in a cloud computing environment.
17 . The system of claim 11 wherein the first system and the second system are implemented in a cloud computing environment.
18 . The system of claim 11 wherein the first system and the second system run asynchronously.
19 . The system of claim 11 wherein the first system and the second system run synchronously.
20 . The system of claim 11 wherein the second system automatically replaces the first system automatically based on a trigger based on time, number of transactions, a measure of data, or a date certain.
