We have a legacy system we are moving to a new infrastructure. The old data has to be ported from mysql to postgres and uses a new data structure and new rules, and is interefaced with a third party CRM system. This project will do a subset of the migration of this data.
Do you mean that the database schemas are different? Do you simply require data from the old system migrated and mapped correctly to the new system, in which case the CRM worries about the queries to retrieve the data? Or do you also require the queries the be written?
I have good experience on both MySql and Postgres. I successfully migrated Multitenancy system from Mysql to Postgres, with that confidence i bid for this project. Indeed this is my first project but i have confidence and proper knowledge to finish this job.
