c# - What is the best way to sync multiple SqlServers to one SQL Server 2005? -

-

i have several client databases use windows application.

i want send data online web site.

the client databases , server database structure different because need add client id column tables in server data base.

i use way sync databases; use application , use c# bulk copy transaction sync databases.

my server database sql server busy , parallel task cannot run.

i work on solution: use triggers after update, delete, insert save changes in 1 table , create sql query send web service sync data.

but must send data first! huge data set (bigger 16mg)

i think can't use replication because structure , primary keys different.

have considered using ssis scheduled data synchronization? can data transformation , bulk inserts easily.
