Distribution Lists and new Exchange Servers

Question

We have migrated our user mailboxes, room mailboxes, and shared mailboxes to exchange online. We still have a few mailboxes that have to remain on prem. We are keeping our distribution lists are on prem. We are hybrid. We us ADSync. We have three on prem exchange 2013 servers and two on prem 2019 hybrid exchange servers. We are in the process of removing the 2013 servers. I am moving the remaining mailboxes to the two hybrid servers. How do I migrate/move the distribution lists to the new servers? Thanks.

Hello @mara2021 ，

How do I migrate/move the distribution lists to the new servers?

For distribution lists, no additional operation is required. DL is not an actual mailbox. And it does not need to be "migrated" according to the Mailbox database. Therefore, after upgrading to Exchange 2019, you only need to confirm that on Exchange 2019 it can be used normally.
