Challenges with T24 Migration
Implementation is extremely
complex and business critical
Data migration is not agile based and
doesn't support Business-IT
collaboration
Mapping multiple core
banking legacy systems into
a single platform system
Challenges data profiling, data
quality & data governance
impacting go-live timelines
No formal migration methodology or
methodology integrated with the implementation
& delivery methodology of T24
Financial loss in the accounting book
due to inaccurate data mapping and
extract specification
Maintenance of delta logs
(data) while conducting
multiple mocks
Unscheduled downtime to
Legacy Services and semiautomated procedures
Engagement from Legacy & T24,
Business & IT subject matter
experts (SMEs), impact time &
cost to engage related resources
Migration is usually seen as one-off activity
leading to a scripted approach with limited
reusability, high risks, longer implementation
plans
Validata Approach
Big Bang
Approach
o V-Conn will migrate all records (bulk import) from the legacy to the T24 tables or
to the DWH
o Validata DB will be used as staging area for the static data
o When doing the import, V-Conn can do the cleansing and validation of the
imported data
o Validata will generate a reconciliation report after the migration
Phased
Approach
o Special adapters will be used to extract the new and modified records and
mitigate them to DWH on a daily basis
o This incremental migration will happen automatically through scheduled jobs
o Following to the migration, a reconciliation of the migrated data in all ETL
processes can be achieved

V-Conn Features
Data Extraction & Loading
Online & offline data extraction and loading from multiple applications
within the same framework
Data Transformation
Validata Mapping Schemas define the mapping and transformation rules.
Data Profiling
Key item for archiving is to identify and understand all relationships in
data
Creates and replicates tables from the legacy systems, storing the data
information accordingly and providing reporting on top of them.
Data Archiving
Prebuilt Migration Mappings forT24
Validation
Scheduling & Job Sequencing
Pre built business mapping knowledge for T24
Field and Data Validation for completeness, proper context, rules
validation and attributes value validation
The migration jobs can be scheduled for single or a repetitive execution
at specified date and time.
Synchronization Service
Real time synchronization of data between two systems
Process Control & Audit
Full audit trail and control over the migration process
Consolidation Reporting
Data import and consolidation from heterogeneous data sources and
from many different applications and platforms
Reconciliation Reporting
Generation of automated reconciliation reports
T24 Reporting Testing
CRF reporting testing and Balance sheet revaluation testing

V-Conn Prebuilt Adapters
A cornerstone of V-Conn architecture is its system integration and interoperability features.
V-Conn design is based upon the concept of a generic core that can communicate freely and
flexibly with other systems using components called adapters.
