Where and when to install Exchange Hybrid
Well this is not as much as a looking for a resolution but what others are doing out there and opinions on a best course of action.
I recently had a friendly conversation about hybrid migration while planning one myself. Currently i am looking at an envrionment running Exchange 2010 (2Mailbox servers, 2CAS/HUB servers). They are migrating to Office 365 and end vision is to only be left with an Exchange 2016 hybrid server for administration, management, you get the picture.
I know that both would work but i am curious what others recommend. Paul Cunningham do you have a recommended approach that you prefer?
1. Would you cut mail flow over to EOP, hybrid with 2010, do the migrations, clean up on prem Exchange, and then install 2016 at the end?
Or
2. Would you install 2016, setup Exchange 2016, cut mail flow to EOP, perform the migrations through Exchange 2016 from the 2010 mailboxes, then just tear down 2010 at the end??
Or
3. Some other way of doing it?
Hi Tom,
Option 2 with a few changes to the process
. Install 2016, setup Exchange 2016, Setup Hybrid, cut mail flow to EOP (Test First), perform the migrations through Exchange 2016 from the 2010 mailboxes, then just tear down 2010 at the end

There is also a 3th option.
Configure Exchange 2010 in Hybrid mode. Then migrate al the users and shared mailboxes to Office 365.
If you have Public folders let them exist in co-existing mode. When the complete migration is done and you public folders are working in Co-existing then upgrade the exchange server which has the hybrid configuration installed to exchange 2016 and you are good to go.
Future approaches are: Make the public folders on 2010 read only give users time to move their data over to a shared mailbox or office group. And when all the Public folders are empty decommission the Exchange 2010 servers.

I agree with this approach and is what I would prefer. But I was having a friendly conversation on what approach people take. Curious what Paul and others recommend.
You can do it both ways. Option 2, as Nuno already mentioned, would be the best and simplest one.
