Migration Services

Today’s state-of-the-art business solutions are tomorrow’s legacy systems. As IBA employs both people with 20-30 years of IT experience and young specialists, we can easily set up teams even for the most challenging projects.

Classification of Migration Projects

Code Migration to Other Platforms and DBs
 zOS/OS2/Win/Unix/Linux → zOS/Win/Unix/Linux
 any DB → SQL DB

1. Application architecture is the same
2. Code is changed partially
3. New GUI (Legacy extension)

Functional Migration (Legacy Transformation)
 C/S appl. (any platform) → WEB-based application
 IBM MVS, IMS, PL1 → IBM AIX, SAP R3, DB/2, ABAP/4

1. Application architecture is different
2. Code is changed completely

Migration Projects Infrastructure

 Multi platform high end servers:z/OS, AIX, Linux, Solaris, NT, 2000, XP
 Migration tools
 Data base environment DB/2
 Knowledge data base

Functional Migration Approach

We usually maintain compatibility of database structure to minimize cost of data migration and to achieve smooth transition by parallel functioning of old and new applications. We also preserve high GUI compatibility to reduce staff re-training expenses. The development is in line with Rational Unified Process.

The course of typical migration projects is the following:
 Reverse engineering: black box analysis
 Functional analysis of the legacy application
 Defining requirements for the legacy application
 Defining additional functional requirements
 Sizing (FP and LoC metrics)
 High-level design and proof-of-concept implementation
 Development and testing
 Pilot deployment in the customer environment
 Production deployment
 Maintenance and support
 Production support

Current Project Record

We have hundreds of completed projects (40000+ person/months) for western clients since 1993. Here are some examples:

Porting Activity

 IBA infrastructure was designed and adopted to perform migration projects in the most efficient way
 Strong IBA methodology and expertise are supported by IBA Project Management and team members
 Processes and procedures for migration and porting projects are defined in the IBA’s ISO 9001:2000 certification documents.
