My guess on this is "no" because the DLs objects are in AD.
We have a 2012R2 domain with Exchange 2010 and are just finishing up an Exchange migration to O365. We are having issues users managing distribution lists through Outlook and for that I need to migrate those to O365. I see a script that does those 1 at a time, but do I need to migrate all DLs/mail contacts to O365 before replacing our Exchange cluster with a new 2016 Exchange server using the HCW? I am guessing those objects will be fine since they are still contained in AD and sync to o365?
We do not want to upgrade the DLs to Office365 groups as I am reading about some corporate people not liking them for some reason
Thanks,
Dave
