Database migration



The aim of this phase is to switch the data base engine to the target (Postgres) one, without any structure transformation (but create indexes,...).

This phase is NOT iterative/incremental: all tables (modules) are migrated in once.



The target technology stack is based on a ORM (django) and won't make use of any database server-specific (MSSQL nor Postgres) features:

  • no Stored Procedure

  • no specific (Transact-SQL) functions 



As a consequence, the migration to Postgres server should be limited to a re-location of the tables (and index re-creation,...)
