asked on

2012R2 Server with 3 Guest OS (All 2012R2) - 1 of 3 Guests is Exchange 2013

Hello,
on a very competent piece of HW - Dell PE R930. Loaded now and can be expanded further.
Have a HV Host 2012R2 - with 3 Guests all 2012R2 as well, one guest is Exchange 2013.

Goal is to bring all servers to OS Server 2019 & Exchange to Exch 2019.
looking for the safest way to do this as well as proper order. adding HW resources to physical server if in place upgrades are not suggested will not be an issue.

looking to takes bite of the elephant vs a no sleep big bang weekend.

appreciate advise and guidance you can provide.

mysuggestion, go with new hardware host, load 2019 hyper-V
Same with VMs. Load new ones and configure them according to their function.

my preferred method as well. they are willing to add HW to the host they have.. they do not want to buy new host.. have to make lemonade out of the lemon if possible. appreciate any other suggestions you may have

Lovely. Perhaps we are shooting too high with Server/Exchange 2019.
what is we adjusted to Windows server 2016 and Exchange server 2016 as the eventual goals? will that make this more doable? cause right now we are going no where with 2019 version goals.

You can go straight to Windows 2019. You just need to do Exchange 2019 first.

When you do the host shouldn't matter.

the host is 2012R2. i can have 2019 or 2016 server guests on 2012R2 HV host?

Yes you can, though running 2019 guest on Hyper-V 2012 R2 doesn't appear to be officially supported, so maybe upgrade the host first.
Lets try it this way.
how long can your system be down?
Where is the hyper-v Host installed?
Are you using a 16GB dual SD-card on which you you have windows server 2012 Hyper-v installed?

Here is the thought, you can import the VMs into hyper-v 2019.

If you are using dual SD's all you would technically need is to pull the two SD's you currently have and insert a new SD.
Then install windows server 2019 Hyper-V on the new SD and then go through the part of importing the VMs, without upgrading their format or you will not be able to roll this back by switching SDs back..

A host/standby to which you can transfer the VMs to maintain options....
Do you use veeam or similar to backup your VMs or are you using the host's wbadmin to backup vms.
A host even for temporary use is optimal in my view.
Hyper-V has never been supported on SD cards.

ok.. let me know if this approach makes sense:

Step 1 - Night 1
HV Host 2012R2 in place upgrade to Server 2019. that leaves me with a 2019 Server as the HV Host and 3 guest all 2012R2, one of the guests have MS Exchange 2013. DC is still 2012R2

Step 2 - Any time
Assuming i have sufficient HW to do so. build a Guest 2019 Server with Exchange 2019.I will join this to same Exchange Org and gradually start moving mailboxes from EXCH1 to EXCH2. DC at this point is still 2012R2.

So from the steps above I created a Host with the ability to have supported 2019 Servers as guests (2012R2 also a supported guest OS). I created a 2019 Exchange server to start migrating my 2013 Exchange data to, at our own pace without drama or major down time.

Step 3 - Any time
Assuming i have sufficient HW to do so. Build a Guest 2019 Server to be Eventually elevated to New DC under 2019 Server.

I have 2 Guests Pending at this point. A File Server that is also the DC and another server that runs their company accounting system (custom built, not off the shelf) . i have no idea how this software will react to an in place upgrade nor do i think the creator/point of contact will be able to answer me if i asked them the question. I can deal with these easily.. was just mostly concerned with the host and exchange and if the above proposed idea makes sense I  have a plan that I can work with.










The R930 has a minimum of 2 physical CPU, and possibly 4. You have lots of CPU available.
What we don't know is how much free RAM, free storage space, and available storage performance to support additional VMs.

assume i have room to work with to expand HW as needed to support the proposed idea.
Thanks, Kevin, it is an unsupported..
Let's try it this way.
Besides the hyper-V host role, what else is running on the host?

Point of question, 2019 hyper-V core install, minus the GUI will lleVe more resources available totge VMs.

Do you have a spare system, HW even older ones on which or to which you can deploy even 2012r2hyper-V to host the current VMs while freeing up the host? At which point you could try the in-place upgrade...... Or install hyper-V fresh?
