Move Archive mailboxes between exchange 2013 and 2019

Assuming we have both primary and archive mailbox enabled

When migrating from Exchange 2013 to Exchange 2016/2019, does moving only the primary to the target Exchange servers i.e. 2016/2019 disconnect access from the archive mailbox after a successful migration

Thank you

    From what I have seen, it should work, however I would not do that except as as temporary measure as you never know if any update or security change within Exchange may break that. I would move both the primary and the archive at the same time to the Exchange 2019.

    You can do that, but I would recommend the archive and primary are both using the same version of Exchange.
