How to Map and Import Multiple tables from Oracle 10G to SQL SERVER 2008

Hello,

I have about 30 tables in an Oracle 10g database that I want to move to SQL Server 2008.

Using the Import and Export Utility I can copy and map this data using the Import and Export data utility and save as a package - YAY!

But as the destination database is under development I want to edit the destination as sometimes field names and data types may change in the destination db. I also want to add mappings and copies from additional tables without having to create new packages.

So how do I Edit a package a) change existing data mapping and b)add new tables created with this utility?

or do I have to convert each table as a separate package (and If so how can I run the 30 packages at once?)

Thanks

Andy
