Moving Exchange 2010 SP3 from Server 2008R2 to new Server 2019 VM
Hello! BryceContento
Your plan of action to tackle this looks good and it will get the job done!
upgrade EX2010 to EX2016 (even now before the new hardware arrives)
- setup new 2019 DC (and demote old 2012 DC) - Dont forget to prep the AD and Schema for Exchange 2016/2019
- install new 2019 Server VM
- install EX2019 into new 2019VM
- migrate EX2016 setup/data to new EX2019
- remove EX2016 server
Since you are in a hybrid with all mailboxes located in Exchange Online , I think your Exchange VM doesnt have to be very "big" performance wise. That is of course, if your MX records are pointed to Exchange Online and all the virtual directories ( Autodiscover etc )
If you got pretty much everything in the cloud then this will be a very stragith forward migration to Exchange 2016/2019
Just dont forget to prep the AD and Schema, and also to re-do the Hybrid Config for the new Exchange Server. And set up the send/Receive connectors.
Also recommend a new SAN Cert with the new VMs FQDN
Hope this goes well!
Let me know if you have futher questions!
Kind Regards

oliwer_sundgren thanks very much for the reply.
From what I've read, there is no longer a "free hybrid license key" for EX2019 only 2016, correct? That means I'll be setting up EX2016 on the new Server 2019 VM.
Am I correct to think that I cannot (or should not) "upgrade" the existing EXC2010 server to 2016 in place? Since it doesn't look like I'll be going to EX2019, does it make sense to even worry about updating the existing EX2010 install at all?
Will prepping the AD ad schema for 2016 adversely effect the existing 2010 install?
- Don't upgrade in place - it's not supported.
Don't go Exchange 2019, you just need Exchange 2016 for hybrid at no Exchange Server cost (OS license still needed) - but this is not true for Exchange 2019 for which you can only buy on Volume Licence and is not free to use for hybrid- Ok since I'm going ex2016 on the new 2019 VM with the free hybrid license, do I need to do anything with the existing ex2010 server (latest CU, upgrade to ex2013, etc) before setting up the new server, or is that just wasted effort since it's going away?
Thanks again all!- Upgrade it - no. But on latest service pack/roll up - that is required before you add Exchange Server 2016 to ensure it keeps working.
