Is MariaDB fully compatible with MySQL?

MariaDB maintains high compatibility with MySQL, especially for versions up to MySQL 5.7 / MariaDB 10.x. Most applications using standard SQL, InnoDB, and the MySQL wire protocol work without modification. However, there are differences in features like JSON handling, default authentication plugins, optimizer behavior, and system variables. Our migration assessment identifies every incompatibility specific to your application so there are no surprises during cutover.

How much downtime is required for a MySQL to MariaDB migration?

With our proven migration methodology, most MySQL to MariaDB migrations require less than 5 minutes of downtime during the final cutover. We achieve this by using replication-based migration where MariaDB acts as a replica of your MySQL source during the data sync phase. The only downtime occurs during the final switchover when we promote MariaDB to primary and redirect application connections.

How do you ensure zero data loss during migration?

We use a multi-layered validation approach: checksums at the table level using pt-table-checksum, row-count verification across all tables, application-level data integrity tests, and continuous replication monitoring throughout the migration. Before cutover, we perform a full data consistency audit comparing source and target databases. Only after all validations pass do we proceed with the final switchover.

Can you migrate from Oracle Database to MariaDB?

Yes, we specialize in Oracle to MariaDB migrations. This involves translating PL/SQL stored procedures to MariaDB-compatible SQL, converting Oracle-specific data types (e.g., NUMBER, VARCHAR2, CLOB) to MariaDB equivalents, rewriting Oracle sequences and triggers, and adapting application queries that use Oracle-specific syntax. We provide a detailed compatibility report and migration plan before any work begins.

What is involved in a MariaDB version upgrade (e.g., 10.x to 11.x)?

MariaDB major version upgrades require careful planning due to changes in default settings, deprecated features, and storage engine improvements. Our upgrade process includes reviewing release notes for breaking changes, testing your workload on the target version in a staging environment, validating all stored procedures and views, running mysql_upgrade, and performing performance regression testing before production cutover.

Do you provide rollback planning in case the migration fails?

Absolutely. Every migration we perform includes a documented rollback plan. During MySQL to MariaDB migrations, we keep the original MySQL instance running and synchronized until the migration is fully validated in production. For version upgrades, we maintain filesystem-level snapshots and logical backups taken immediately before the upgrade. Rollback procedures are tested in staging before any production migration begins.

▸ SEQUENCE / AUTO_INCREMENT divergence - Oracle SEQUENCE objects have no direct equivalent in MariaDB's AUTO_INCREMENT model - IDs collide or wrap differently after you land on MariaDB unless they're converted to MariaDB SEQUENCE objects or AUTO_INCREMENT correctly.
▸ JSON column behaviour drift - MySQL's binary JSON normalizes and key-sorts objects, while MariaDB's JSON is a text-based LONGTEXT alias - JSON_* function behaviour and object-key ordering can differ after you land on MariaDB.
▸ Galera flow control mid-SST - Adding a donor for cluster-mode migration triggers flow control; writes stall cluster-wide and the SST itself never completes.

Smooth Database Migration

MariaDBMigration Services

In short: A MariaDB migration moves MySQL or Oracle databases to MariaDB - or upgrades MariaDB versions (10.x→11.x) - through a four-phase process: assessment and planning, schema and compatibility analysis, replication-based data migration with checksum validation, and a final cutover. The approach delivers zero data loss with under five minutes of downtime.

Migrate to MariaDB with confidence. Whether you're switching from MySQL, Oracle, or upgrading MariaDB versions, we deliver zero data loss migrations with minimal downtime.

Our Migration Process

A proven four-phase methodology that ensures every migration is executed with precision, validated thoroughly, and completed with minimal disruption.

Assessment & Planning

Comprehensive analysis of your source database, application dependencies, data volumes, and migration complexity. We deliver a detailed migration plan with timeline, risk assessment, and rollback strategy.

Schema & Compatibility Analysis

Detailed schema review, data type mapping, stored procedure conversion, and query compatibility testing. We identify and resolve every incompatibility before touching production data.

Data Migration & Validation

Replication-based data synchronization with continuous validation. Table-level checksums, row counts, and application-level integrity tests confirm zero data loss throughout the process.

Cutover & Go-Live

Coordinated switchover with less than 5 minutes downtime. Application connection redirection, final consistency verification, performance monitoring, and rollback readiness throughout.

Why Choose Our MariaDB Migration Services?

Every migration is backed by rigorous testing, transparent communication, and battle-tested tooling to ensure a smooth transition with no surprises.

Minimal Downtime (<5 Minutes)

Our replication-based migration approach keeps your source database running throughout the process. The only downtime occurs during the final cutover when we redirect application connections to the new MariaDB instance.

Comprehensive Compatibility Testing

We test every query, stored procedure, view, and trigger against the target MariaDB version. Automated compatibility reports highlight issues before migration begins, so nothing breaks in production.

Documented Rollback Planning

Every migration includes a fully tested rollback plan. We maintain your original database in sync until the migration is validated in production, giving you a safe path back at any point during the process.

Multi-Layer Data Validation

Zero data loss is verified through table-level checksums, row-count comparisons, referential integrity checks, and application-level data validation tests run before, during, and after migration.
