Do I need to move 'Client Access' and 'Hub Transport' from Exchange 2010 to Exchange 2016?

I recently installed Exchange 2016 and migrated all users from Exchange 2010 to 2016.
I plan to uninstall Exchange 2010 and remove it from domain before decommissioning the Exchange 2010 server.

But I noticed in EAC that the Exchange 2010 has the server roles: 'Maibox', Client Access' and 'Hub Transport' wheres Exchange 2016 only has the 'Mailbox' role.

I already tested by shutting down the Exchange 2010 server and everything including send/receive works fine on Exchange 2016.

So do I need to do anything before getting rid of the Exchange 2010 server?

No, there is nothing else to do. Those roles will already be installed by default on the Exchange 2016 servers.

if you have all mail routing to Exchange 2016 you are now good to remove Exchange 2010 servers by uninstalling The exchange software from those servers.

Exchange 2010 and Exchange 2016 has architectural changes in roles, so there is no need to transfer anything from 2010 server, just disable exchange 2010 services once migration is complete for a week, verify functionality of migrated users and then decomission exchange 2010 server gracefully.
