Hi!,
It is not cleared in your posting what exactly you want to achieve. If it was about data synchronization please read further or just needed to switch the database connection from one db to another that too i can deliver in less time(time mentioned in bid is max time).
I have recently developed data synchornization component. But it is built on top of dotnet. It transfer 10 MB data in few neno seconds. that i have tested. I had explored n developed so many other synchronization possible solutions. If interested please let me know.
Thanks,
Hitesh
