MIGRATION PROCESS

A Structured Migration Approach

A migration can be divided into clear stages to make the process easier to manage and validate.

01

Assess

Review the source database, objects, dependencies and requirements.

02

Plan

Define the target platform, conversion approach and migration activities.

03

Convert

Convert schema, SQL, procedural code and required database objects.

04

Migrate

Move data to the target environment and perform required transformation.

05

Validate

Compare source and target data and investigate migration differences.

06

Optimize

Review queries, indexes and database configuration after migration.
