Data Migration

Data migration is the transfer of data from legacy platform(s) to a current platform. It is normally required when the systems on which your business depends are threatened with obsolescence, or during company mergers or expansions. Whether you need to migrate your company data because your servers, database, storage arrays, or all of these are outdated, the impact is the same - the survival of your business depends upon the data, not on the outdated system where it is housed. A smooth transition from old to new quickly becomes a matter of urgency.

OnX consultants are well-practiced in the arts and imperatives of data migration. A migration task is analyzed from the joint perspective of the business issues and technical issues raised in the initial assessment. All current procedures and processes are identified, business impacts are defined to ensure mitigation during execution, and sizing and design of the migration infrastructure are detailed beforehand. Using our XProcess methodology, clients are presented with a plan in eight phases:

Phase 1 - server, storage, and data assessment
Phase 2 - High-level migration strategy
Phase 3 - Detailed migration process development and prototype
Phase 4 - Detailed execution plan development
Phase 5 - Migration infrastructure build
Phase 6 - Migration process execution
Phase 7 - Data validation and cleanup
Phase 8 - Decommissioning of migration infrastructure

Our consultants perform data migrations between:

Servers - UNIX to UNIX, similar or dissimilar vendors (e.g., HP-UX 10 to HP-UX 11, or AIX to Solaris); UNIX to Linux; UNIX to NT; NT to 2000, 2003.
Database - database to database, whether sourced from the same or different vendors (e.g., Sybase to SQL2000, or Oracle 8 to Oracle 9).
Storage - array to array (similar or dissimilar vendors, e.g., HP XP256 to XP1024, or EMC to HP); distributed to centralized storage (DAS to SAN).
