Discovery & Assessment

A thorough inventory analysis of your existing database environment, including dependency mapping and performance baselining.

Technical Specifications:

  • Schema analysis (tables, indexes, views, stored procedures).
  • Data volume and growth rate projection.
  • Workload profiling (read/write ratios, query patterns).
  • Security and compliance requirements review.

Potential Challenges:

  • Undocumented dependencies between applications and database.
  • Legacy database versions with limited introspection tools.
  • Identifying all sensitive data for compliance (PII, PCI).

Migration Strategy & Architecture

Detailed design of the target database schema, defining the migration approach (homogeneous/heterogeneous), and comprehensive rollback planning.

Technical Specifications:

  • Target platform (cloud/on-prem, specific database engine).
  • Data type mapping and conversion rules.
  • Index and partition strategy for performance.
  • High availability and disaster recovery architecture.

Potential Challenges:

  • Complex data type mismatches requiring custom scripts.
  • Ensuring application compatibility with new database features.
  • Designing a robust rollback plan for minimal data loss.

construction

Pre-Migration Preparation

Setting up the target environment, configuring network connectivity, and conducting exhaustive connectivity and performance tests.

Technical Specifications:

  • Provisioning compute, storage, and network resources.
  • Firewall rules, VPC peering, and private endpoint configuration.
  • Database parameter group and security group setup.
  • Load testing and benchmarking against baseline.

Potential Challenges:

  • Network latency and throughput bottlenecks.
  • Security policy enforcement across environments.
  • Resource provisioning and scaling limitations.

schema

Schema & Object Migration

Converting and migrating all database objects, including tables, indexes, views, functions, and stored procedures, followed by rigorous validation.

Technical Specifications:

  • DDL (Data Definition Language) script generation and execution.
  • Validation of object counts, definitions, and permissions.
  • Refactoring of incompatible stored procedures/functions.
  • Foreign key and constraint integrity checks.

Potential Challenges:

  • Proprietary database features not supported in target.
  • Complex PL/SQL or T-SQL code requiring manual refactoring.
  • Ensuring referential integrity across migrated schemas.

Data Migration Execution

Executing the bulk load of historical data and setting up Change Data Capture (CDC) for continuous synchronization to minimize downtime.

Technical Specifications:

  • Data extraction methods (export/import, native tools, replication).
  • ETL (Extract, Transform, Load) pipelines for data cleansing and transformation.
  • CDC setup using logical replication or transaction logs.
  • Monitoring data latency and throughput during sync.

Potential Challenges:

  • Managing large data volumes and migration window constraints.
  • Network interruptions affecting data transfer integrity.
  • Ensuring transactional consistency during CDC.

fact_check

Validation & Testing

Comprehensive data integrity checks, reconciliation, and performance testing to ensure the target database mirrors the source and meets performance SLAs.

Technical Specifications:

  • Row count and checksum validation across source and target.
  • Query execution time comparisons and stress testing.
  • Application integration testing and user acceptance testing (UAT).
  • Data quality and referential integrity checks.

Potential Challenges:

  • Discrepancies in data type handling or character sets.
  • Simulating peak production load for accurate performance testing.
  • Coordinating UAT across multiple business units.

Cutover & Go-Live

The final switchover, involving a brief outage (if any), final data synchronization, and redirecting application traffic to the new database.

Technical Specifications:

  • Application shutdown and final CDC synchronization.
  • DNS record updates and load balancer reconfigurations.
  • Post-cutover health checks and smoke tests.
  • Rollback trigger conditions and procedures.

Potential Challenges:

  • Unexpected application connection issues post-switchover.
  • Propagation delays in DNS changes.
  • Coordinating cutover with minimal business impact.

Post-Migration Optimization

Continuous monitoring, performance tuning, and comprehensive knowledge transfer to your team for ongoing operational excellence.

Technical Specifications:

  • Establishing new monitoring and alerting dashboards.
  • Ongoing query optimization and index tuning.
  • Capacity planning and cost optimization strategies.
  • Documentation and training for database administrators.

Potential Challenges:

  • Unforeseen performance regressions with specific workloads.
  • Adapting to new cloud-native database features and best practices.
  • Ensuring internal teams are fully equipped to manage the new environment.

Database Migration Services – FAQs

What is database migration?

Database migration is the process of securely moving data, schemas, and database objects from one database platform to another, such as on-premise to cloud or between cloud providers.

Can database migration be done with zero downtime?

Yes. AvierIT Tech uses Change Data Capture (CDC) and parallel replication strategies to ensure near-zero or zero downtime during enterprise database migrations.

Which databases do you support?

We support PostgreSQL, MySQL, Oracle, SQL Server, MongoDB, Snowflake, and cloud platforms including AWS, Azure, and Google Cloud.

How long does a database migration take?

Migration timelines depend on data volume, complexity, and compliance needs. Most enterprise migrations take between a few days to several weeks.

Is database migration secure?

Yes. We follow SOC2, GDPR, and ISO-27001 compliant security practices including encryption, access control, and audit logging.
