Disconnected from Dynamics365 Online

Hi,

I'm running a Data Migration from an on-premise system (not CRM) and transforming the data into CRM entities.

I've noticed if the migration continues for a significant period of time, I eventually start getting fault exceptions from Dynamics online.

I am not hammering the system - maybe 4 inserts per second against a sandbox tenant.

Is there some way to persist my connection so I don't get kicked out?

I would have thought buy simply logging into the tenant and inserting the records it would have kept my session alive?

Thank you - Greg
