The only supported method with Exchange 2010 is use Exchange tools to update attributes when you are syncing from AD to AAD. There is a way to remove Exchange on-premises for Exchange Server 2019 (details here: https://techcommunity.microsoft.com/t5/exchange-team-blog/removing-your-last-exchange-server-faq/ba-p/3455411)
There is no option to enable remote mailboxes without having Exchange tools installed. Some more details on that scenario can be found here https://learn.microsoft.com/en-gb/Exchange/manage-hybrid-exchange-recipients-with-management-tools

Hi Dan,

Thank you for that, would the best process be to upgrade through all the servers sequentially to exchange 2019 through 2013 and 2016 or to uninstall exchange 2010 and install 2019 directly,

Thank you for your help
