Transfer Data Between Two Different SQL Server Instances in Separate Servers

Hello,

Is there another secured way to transfer data between 2 different SQL server instances residing in 2 separate boxes besides linking them?  What if they are different versions and the OS in the boxes is different as well?  For example:



Boxes      OS                                                SQL Server version

Box1      Windows Server 2008 SP1            SQL Server 2008
Box2      Windows Server 2012            SQL Server 2012

We need to pass data between one SQL server instance to another via triggers and stored procedures. Can this be done without linking them?

Thanks.

you need to link them, if you have to use triggers / stored procedures, If you just need to sync the data from one to another, you can setup  log shipping, in that case the second server can act in a read only / stand by mode.

SQL Server Information Services (SSIS) is also an option, where you can create a package that connects to both source and destination SQL boxes, and create Data Flow Tasks that move data between them.

You should also look at Replication, rather than trying to write and maintain your own code to do this (:shudder:).

Hi,
You can create linked server on one server to access data from another server.

@HuaMinChen, this is what he wants to avoid to do.

If you want a synchronous solution, the Replication it's my advice. For an asynchronous solution you can also use Replication or follow Jim's suggestion to create a SSIS package.
