How to migrate Data from SQL Server to PostgreSQL

Question

I know that is a lot of manual work to translate the SQL queries from SQL Server to PostgreSQL. But I was wondering, if there is the more effective way to insert DateTime values from SQL Server to timestamp format in PostgreSQL. Because I need to work with 900 entries.

SQL Server format:

CAST(0x00009DFE00000000 AS DateTime)

POSTGRESQL format:

???

Answer 1

I'd use any kind of neutral dump tool, I've personally used this one:

for migrations between databases, never used it with SQL Server but provided there is an active record adapter for SQL SERVER it should work too.

I don't know if you are limited to use only queries or commands, but if not you may wanna try do some ETL. There are many tools you could use. I did some simple data migration from SQL server to PostgreSQL a few years ago with Pentaho ETL.
