Porting from Oracle to MySQL

A potential customer asked my about porting her application from Oracle Database to MySQL.

I always try to start with the "why" (a dear friend bought me this book, recommended: http://www.amazon.com/Start-Why-Leaders-Inspire-Everyone/dp/1591846447).

She said "cloud!". I said "OK!".

I conducted a short research, found many things in many places all over the place, brought them to a nice email I sent her back and then thought I'll post it here and make it public as it might be useful for us all. If you feel that I missed something, add comments, send feedback. 

These are the leading tools to do the actual migration of the data structure, data export/import, sprocs, triggers, etc.:

1. MySQL Workbench has a migration feature: http://www.mysql.com/products/workbench/migrate/
2. MySQLYog can be used to migrate: http://tkurek.blogspot.com/2013/04/migrate-oracle-to-mysql.html  (already in the conversation in the second comment there)
3. Navicat can be used to migrate: http://www.navicat.com/products/navicat-for-mysql
4. Tungsten support Oracle-to-MySQL replication: http://www.continuent.com/downloads/software
5. Focused data migrators:

The way I see it, migrating the data is 15% of a database porting project. Efforts are in (partial list):

1. Porting drivers and driver behavior in the app code
2. Porting SQL commands all around the app code
1. Conversion of non-standard SQL flavor
2. Work-around restrictions and non-supported commands
3. Ecosystem, monitoring, tuning, tools, scripts, hardware best practices, ops skills, dev skills

Way before the migration of the data on d-day.

A lot of services, some tools. Services-wise I see around:

1. Pythian: http://www.percona.com/live/mysql-conference-2012/sessions/oracle-mysql-migration
2. Baron (Percona): http://www.xaprb.com/blog/2009/03/13/50-things-to-know-before-migrating-oracle-to-mysql/

I bet the big SIs (Accenture et al) are strong in this game, as those would be the default go-to service provider for the Oracle shops.
