Following are high level tasks will be performed as part of consolidation process or data migration activity from existing customer’s systems into newly consolidated Database
Source & Target
Analysis and Mapping
Analyse the source databases and
target database and prepare mapping
document and template to capture
data and migrate over
Business Filters
Analyse and identify the Business
filter and transformation logics
and develop a technical approach.
Develop Data Migration Scripts
Oracle SQL/PL SQL scripts will be
developed to perform data migration
source data files to target database
like Metasolv M6.2.x.
Loading into Staging Area
Execute the migration scripts to load
data into staging schema, which is
being identical to target database

Waterfall model of execution
works best, in simple system to

Agile frameworks like scaled
agile is useful with increasing
complexity of migrations
Systems Integration Test(SIT) is
executed based on business

by csp business units
Performance test is mandatory
when data getting loaded is huge
and for mission critical systems

Breaking a data block into smaller chunks by following a set of rules, so that it can be more easily interpreted, managed, or transmitted by a computer.
Spread sheet programs, for example, parse a data to fit it into a cell of certain size.
