One is live and SQLSVR2 is a backup. From time to time, I may need to switch them so I am writing a sync application that uses ADO .Net to read the modified/new rows from SQLSVR1->Table A and update/insert/delete them from SQLSVR2->Table A. These tables have a lot of columns(250+) which is why I want to use ADO. I was using the MS Data Set Generator to generate the dataset/data tables for me. The problem that I am having is that I cannot copy one data table from SQLSVR1 to a data table from SQLSVR2. I thought that I could use the UPDATE, DELETE and INSERT methods in the appropriate data adapter if I could populate the data table on SQLSVR2. Has anyone ever tried to do this or can anyone suggest an alternative solution?

If two databases are on the same server, triggers can be used to easily achieve data synchronization. Are SQLSVR1 and SQLSVR2 here Azure SQL Database? Are they on the same server?
