Pull in remote data without sending data from server

HI,

Sync has been working well for months.

But... an external contractor has done something to modify 800,000+ records.

Unfortunately that change is being pushed to 20-or-so remote clients and causing MirrorSync to collapse under the weight.

I can have the remote users simply download a new copy of the database, but many of them have data to upload first.

Is there any way I can have the server gather the data from the remote clients only without trying to push down the 800K+ records down to them?

Thanks,

ft.
