Exchange 2013 -> Hybrid migration to EXO
first step would be to setup a new server 2019 exchange setup hcw on this new server.
migrate all mailboxes to and required settings over to the new server. decommision the old servers. and migrate the mailboxes from the 2019 to exchange online. that is the supported method. this way you'll have a management server that is supported by MS.

Thanks for the quick responses! So first upgrade and migrate to Exchange 2019 and then to EXO. The goal is to completely remove the on-prem Exchange environment. Is it also possible to install only new Exchange 2019 VM. Make it a member of the current Exchange 2013 and run the Hybrid setup on the Exchange 2019? Then migrate the mailboxes to EXO and then uninstall the on-prem environment? Thank you in advance again!
- Hi !
everything is possible but I personally would stick to the recommended and supported methods. Because if something goes wrong you can find troubleshooting guides online. You can completely remove the Exchange 2019 afterwards but you will have to setup the snap in as mentioned by Andres. Hi Ivarious90
>The goal is to completely remove the on-prem Exchange environment
You can do that. But then you only install the Exchange 2019 Management Tools and Manage the Recipients via the SnapIn
If you go down that route, make sure you have an alternative for your Applications that use Exchange as an SMTServer or SMTPRelay.

Make sure you follow the Virtualization Requirements

You should still able to Migrate from Exchange 2013 (no support as already mentioned)
Depending on the Amount of Mailboxes, needed Storage for Mailboxes and your Project Plan you might want first to install a Exchange 2019 Server.
Adding a new Server in the Exchange Organization requires Hybrid Wizard to run.
Move all Mailboxes to the new Server and Migrate from there also takes Time.
Be aware that Microsoft will start throteling or block old Servers. Starting with Exchange 2007Regards
