Phased Migration
We migrate data in planned phases, allowing for a more gradual approach to data migration.
- Pro: Minimizes disruption to ongoing operations.
- Pro: Better risk management as issues can be identified & addressed in manageable portions.
- Con: Time consuming and delay in reaping the benefits of the data migration process.
- Con: Managing coexistence between old & new systems when migrating can be challenging.
Big Bang Migration
Opposed to phased migration, in our Big Bang Migration services, all data is migrated at once.
- Pro: Rapid transition, resulting in earlier accessibility to new systems.
- Pro: Easier to manage a single migration event for resource allocation & project management.
- Con: Higher risk of downtime during the migration process.
- Con: Validating one consolidated system may pose challenges in addressing the issue.
Parallel Migration
Parallel Migration involves running the legacy and modern systems simultaneously during the migration process.
- Pro: Minimizing downtime and maintaining business continuity can be challenging.
- Pro: Parallel migration results in efficient validation as both systems can be compared in real-time.
- Con: Managing two parallel systems can introduce business and synchronization complexities.
- Con: Running two systems parallel will be resource intensive requiring additional resources.
Incremental Migration
Incremental migration allows organizations to only migrate parts of the overall systems that require change or upgradation.
- Pro: Minimized downtime as only the changes due to selective migration process.
- Pro: Reduce the complexity of the data migration process with more manageable data sets.
- Con: Planning incremental migrations requires careful consideration about dependencies.
- Con: Ensuring data consistency between old and new data migration models can be challenging.
