Quick Lauch

Once you stored conversion settings into profile you can run the program in Quick Launch mode. Just launch Windows Explorer and double-click on the profile description (.m2p) file with left mouse button. This will cause MSSQL-to-PostgreSQL wizard to launch conversion loading the necessary settings from the specified profile. Then you will be taken right to the screen with progress of conversion without entering all conversion settings.


MSSQL-to-PostgreSQL implements synchronization as combination of insert MS SQL records that are missing in PostgreSQL table and update existing PostgreSQL records with MS SQL data. For synchronization purpose source and destination tables must have identical structures and have primary key or unique index defined. Assume both MS SQL and PostgreSQL databases have table "People" defined as below:

	FName VARCHAR(50),
	LName VARCHAR(50), 
	EMail VARCHAR(50), 
        Primary Key (ID)

This table has the following contents in MS SQL database:

2  Andrew  White
3  Phil  Johnson

In PostgreSQL database:

1  John  Smith
2  Andrew  White

After migrating MS SQL data to PostgreSQL in "Synchronize" mode MS SQL table is kept untouched and PostgreSQL table is modified as (pay attention to the cell marked red):

1  John  Smith
2  Andrew  White
3  Phil  Johnson

Try before you buy

Still not sure the program fits your needs? Try free demo version with limited features. It will allow you to convert only five records for each database table, it does NOT convert queries/views and foreign keys. Test the quality of the demo and come back to place an order if satisfied with the results.
