Hello,
I have all mailboxes from an Exchange onpremise to Exchange onine.
How can I cleanly uninstall Exchange onpremise and remove it from the domain?
Thanks

Thanks for the answers.
Can I go this way

to uninstall the Exchange onPremise?
I have only one try and have to do it in a productive environment.

I guess there is a bit more work, as you will need to update your MX and CName record for the autodiscover.
Check this one

and this is also good

Update your MX and CName record for the autodiscover is already done.
The migriation was not with hybrid exchange. I created not a hybrid exchange enviroment. Just use the migrate button in exchange online.

I guess I wrote a reply, but then it disappears or I replied somewhere else to someone else :), Anyway
If this approach you used then it's OK, confirm your DNS settings, and remove the connectors.
Shutdown your exchange server for some time and see what will happen, if all is fine, then you can continue with the uninstall process
