We moved our 400 table (at the time: now 530+) table to SQL with not much trouble. But we had planned for it. Everything was written in views, so the DBC could be changed out at will to a "remote" DBC.

You mention using "data objects": you can use SQL server as tables by using SPT and making the cursors modifiable, etc. Naomi will pipe in with the reference. <s>

So, a lot depends on how your app is currently written.
