Hi @MarcoMandricardo-1414 ,

I think you should check the version of Exchange 2010 first. Because the minimum version of Exchange 2010 required to coexist with Exchange 2016 is SP3 RU11.

Run Get-ExchangeServer in EMS, and compare the Build number with Exchange Server 2010 build numbers, if the version doesn’t reach the requirement, you should update it to at least SP3 RU11 first.

Then you can do the following steps for coexistence and migration:
1. Prepare SBS 2011 and raise domain function level.
2. Install Windows Server 2016 and join domain.
3. Promote Windows Server 2016 as domain controller.
4. Install Exchange 2016 on another Windows Server.
5. Configure Exchange 2016 and migrate mailboxes and public folders to it. Exchange Deployment Assistant
6. Uninstall Exchange 2010 on SBS 2011.

These articles have a detailed guidance for the migration: SBS Exchange 2010 Update and How to Migrate SBS 2011 to Server 2016 (Exchange 2016)?, I think they would help you.

Also, I think that you need to buy "Migration Kit" from Microsoft to convert your SBS Server into corresponding Windows Server Standard Edition + SQL Server + Exchange Server.

Without that I think you'll stuck at step 3.

hi @ZhengqiLou-MSFT and @cheong00 ,
thanks for your answer,
in my company we use CodeTwo to perform this migration,
i have already use it, but in this scenario, with exchange on the same domain, i think that i need sure to perform update to SP3 RU11, then install new exchange 2016 server and after migrate with CodeTwo,
do you ever have experience in this scenario with AD? we have already prepare new domain controller 2016.
there are no microsoft guide about Uninstall Exchange 2010 on SBS 2011 and after remove it?

Hi @MarcoMandricardo-1414 ,

Sorry for the delay of this reply.

Yes you should update your Exchange to SP3 CU11 to coexist with Exchange 2016, but you can first use Get-ExchangeServer to check which version you’re using.
And sorry that I have never used CodeTwo to do the migration before. Besides, according to Microsoft product strategy, we only provide support for Microsoft products. If you have questions about the third-party software, I think you can try to contact with their support center to get help.

If you don’t use Exchange 2010 and SBS2011, you can directly remove them after migration and configuration, make sure CAS FQDNs, mail flow connectors and virtual directory urls are pointing to Exchange 2016.
The Exchange Deployment Assistant will tell you how to migrate all needed mailboxes, records, URLs and other items to the new server, so you could directly remove the legacy Exchange 2010 after the migration.
Also you can read this article: Removing Exchange 2010 after Coexistence with Exchange 2013, it is same in Exchange 2016.

I found a guidance of the migration from Exchange 2010 to Exchange 2016 using CodeTwo: How to migrate Exchange 2010 to 2016? A step-by-step guide. Hope it will help you.

Hi @MarcoMandricardo-1414 ,

Oh i hope i didn't misunderstand this:
71030-image.png
This means it could help you do the migration directly whatever the Exchange version is.

Seems it's right.

Sorry again, since i don't know more about CodeTwo, i think you could open a thread on SpiceWorks, since there they have CodeTwo as a partner.

Lou

But if you don't upgrade to CU11, you won't be able to install Exchange 2016 in the same domain or maybe you installed it successfully, the legacy Exchange will retrieve a failure, since these two versions could not coexist.
So it's not suggested to install Ex 2016 with SP1, if you want to use CodeTwo to do the migration, you may not have to upgrade it first. If you don't use CodeTwo, then it is necessary to upgrade to SP3 CU11.
