Exchange 2010 coexistance with Exchange 2013- Decommission

Hi All,

We have coexistance with Exchange 2010 and Exchange 2013.

We have completed the migration and public folder move.

Now we are in phase of Decommission.

I hav a query- Do we need to do anything for Email Address policy , Send connectors, accepted domains whihc is in Exchagne 2010.

We have not done any changes in this , just we have modify send connectors.

Pleaser suggest.
