Migrating Win 2011 SBS to Win 2019 Std when Exchange is not an issue.

Hello All
I have a Win SBS 2011 server and Exchange has been moved to MS 365 so I do not have to worry about moving Exchange from the SBS 2011 to the 2019 server. Should I go thru a migration or just start fresh on the 2019 server . If migration path is the choice what would be the best process to go about this when migrating the following:

FSMO roles
Active Directory Domain Services
DNS
DHCP
Folders, folders and shares
Users
Computers
Security and/or permissions


Thank you for any thoughts

For the domain controller. The two prerequisites to introducing the first 2019 domain controller are that domain functional level needs to be 2008 or higher and older sysvol FRS replication needs to have been migrated to DFSR
https://techcommunity.microsoft.com/t5/Storage-at-Microsoft/Streamlined-Migration-of-FRS-to-DFSR-SYSVOL/ba-p/425405

I'd use dcdiag / repadmin tools to verify health correcting all errors found before starting any operations. Then stand up the new 2019, patch it fully, license it, join existing domain, add active directory domain services, promote it also making it a GC (recommended), transfer FSMO roles over (optional), transfer pdc emulator role (optional), use dcdiag / repadmin tools to again verify health, when all is good you can decommission / demote old one.

I'd suggest asking the DHCP migration question here
https://docs.microsoft.com/en-us/answers/topics/windows-dhcp-dns.html

and the storage migration question here
https://docs.microsoft.com/en-us/answers/topics/windows-server-storage.html

HI MacJohnsonII-7805,

Since server 2019 standard has removed server essentials experience role, it is by design.
So the steps for migration is similar as the steps for migration from SBS 2011/server 2008r2 to server 2019 std.

we can refer below AD and DHCP migration video to do migration steps.

There are steps (including but not limited to these steps) listed here:
(1)Full system backup for SBS 2011 (System state & Data)
(2)Installing Server 2019 std on new Server and add it to existed SBS domain.
(3)Migrating Folders, folders and shares from SBS2011 to server 2019STD

(4)Migrating DHCP to hardware router or server 2019 std and check if migration successfully.
(5)Raising Forest and Domain Functional Level Windows Server 2008, then migrate FRS to DFSR ,before promote w2019 as replica DC.
(6)Promoting Server 2019 to PDC (Primary Domain Controller)
(7)checking replication between both DC servers.
(8)Transfering all FSMO from SBS2011 to W2019
(9)Removing AD service from SBS2011
(10)Unjoining all Computers Workstations from SBS 2011 and join them to server 2019STD
(11)Removing SBS2011 server from the network.

JiaYou,
Thank you for the detailed instructions.
I didn't see your post until recently when I asked DSPatrick some questions in reference to the migration steps.
Your info gives me a more secure feeling with what am going to attempt to do. I will be working on this today but I wanted to know is the original server going to be available to users during this process and when in the process besides step 11 removing SBS2011 from network will it not be available anymore.

I've got some reading to do but I will let you know how things went I will hopefully be doing the migration next Friday over the weekend.

Again Thanks for your time and the information.

HI HI MacJohnsonII-7805,

in general, SBS2011 can only be acted as PDC with Full FSMO, this behavior is by design, so removing SBS2011 server from the network is a must. If you still want to use it in your current network, i think it need to be in other forest.

Hello Jai-You and All,
Again many thanks for your steps.
I feel foolish because I missed a step and wanted to know if I could keep going after correcting the mistake or do I have to start over.
My mistake is I forgot to raise the functional level of the DC from Win server 2003 to Win Server 2008 and the promotion of the new ADC was stopped.
Can I just raise the functional level of the DC to Server 2008 or do I have to remove the AD role from the new ADC then raise the functional level of the DC to 2008 the add the AD role back to the new ADC?

Thank you for your thoughts

Then you'll nee to remove the 2019 domain controller then confirm health is 100% if all is good then do the FRS->DFSR migration
https://techcommunity.microsoft.com/t5/Storage-at-Microsoft/Streamlined-Migration-of-FRS-to-DFSR-SYSVOL/ba-p/425405
and after completion check health is 100% again, then you can raise DFL to at least 2008 level, then you can introduce a 2019 domain controller. (follow the detailed steps in my reply above)

Thank you for your time.
To be clear.
I need to
1. Remove the AD role from the new 2019 server.
2. Next use dcdiag / repadmin tools to verify health of 2011 SBS or 2019 server?
3. Then stand up the new 2019, patch it fully, license it ( It already is up and patched after removing ADS)
4. Then re-join it to the existing domain,
5. Re Add active directory domain services, promote it also making it a GC (recommended), transfer FSMO roles over (optional), transfer pdc emulator role (optional), use dcdiag / repadmin tools to again verify health, when all is good you can decommission / demote old one.

Do I raised the domain functional level of my 2011 SBS from 2003 to 2008 after I remove the ADS role from 2019 server?

Thanks for your assistance

I have run the dcdiag.exe and it seems like most things passed except for some unable to communicate with a pc and a NAS device message
would you be agreeable to look at the output file and advise me as to the severity of the errors?
Thank You
