What is the easiest way of oracle to sql server migration?
One of our products supports both Oracle and SQL Server as database backend. We have a customer who wishes to switch from an Oracle backend to Microsoft SQL Server, which isn't a typical transition for us.
What is the easiest way to get all the data from the entire Oracle Schema into the SQL Server database? The schema only contains plain old tables and nothing fancy. There might be one or two stored procedures that we'll have no problem migrating by hand. I could use Oracle's SQLDeveloper to export the table data as CREATE and INSERT statements, but these won't match the Syntax used on SQL Server and I am not looking forward to having to manually fix the syntax errors.
Here are the step to follow oracle to sql server migration:
- Create a new SSMA project.
- Connect to the Oracle database server.
- Connect to an instance of SQL Server.
- Map Oracle database schemas to SQL Server database schemas.
- I actually used the "Microsoft SQL Server Migration Assistant (SSMA)" from MS once for this and it actually did what it promised to do: SQL Server Migration Assistant for Oracle (documentation) Microsoft SQL Server Migration Assistant v6.0 for Oracle (download) SQL Server Migration Assistant (SSMA) Team's Blog However in my case it was not as fast as I would have expected for a 80 GB Oracle-DB (4 hours or something) and I had to do some manual steps afterwards, but the application was developed in hell anyway (one table had 90+ columns and 100+ indices).
