Exchange 2019 - Exchange SE - In-Place upgrade
Hello,
we’re currently running an Exchange Server 2019 hybrid environment (DAG on-prem + Exchange Online) with a few on-prem user mailboxes used for automated system communications (SMTP) - the mailboxes are not being used in Outlook. We migrated from Exchange 2016 to Exchange 2019, using a trial installation of Exchange 2019, which has expired.
We are planning to upgrade to Exchange Server Subscription Edition (SE) and want to ensure the following is supported:
- Can we perform an in-place upgrade from the expired Exchange 2019 trial to Exchange Server SE, or do we need to relicense/reactivate Exchange 2019 first?
- What is the right / best action plan for us in this case
Kindest Regards
Leon

Hello,
It depends on your current patch level. If you have at least CU14, it should work. If not, it may not be possible to apply the update due to the trial expiration. In that case, there are only two options: enter a valid product key, or install Exchange SE on new machines and migrate the mailboxes from Exchange 2019 to SE.

I assume you will be able to upgrade...if not it should error during the prerequisite check. Having said that, it probably doesn't meet Microsoft requirements, so I'd recommend licensing the server correctly prior to upgrading.
