Upgrade win2008 to win2012 error:could not update registry data

Windows could not update registry data in the installation.
I have searched online but I find nothing to assist.
The first error I got was a E: drive not big enough to do an upgrade.
So I decreased the size of C; drive by 100MB and then applied it to the E: drive.
I first defragmented both drives before sizing/desizing of C: and E: drive.
The E: drive is the "System Reserved" drive for Win 2008.
It used to be 100MB i changed it to 195MB.
I used Easus Partition Master.
I need to upgrade because I need to install new version of database that is only compatible withWin2012.
I can not do a Clean install because client machines register with application database running on this Win2008 machine.

All this is on a VMenvironment

Can you please go through below blog and check accordingly,

In this scenario, We need to analyse CheckSUR.log to troubleshoot further.

Before perform checksSUR activity,

Run sfc /scannow in Evaluated command prompt and check if that fixes the problem

ASKER

MS, I should run the DISM.exe?
I did so and got mssg "the restorehelath option is not recognized in this context.

Hi, Have you checked sfc /scannow ?

We can wait for further suggestions from other Experts.

ASKER

no, I have not.
I will try that now.
Hopefully its available without download with an escalated windows command prompt

ASKER

i disabled all non-windows services and apps.
I tried to install win2008 as an upgrade to repair it but it did not work.
i got the same error.
will do above intructions of /sfc?

ASKER

what should I do after it finishes scanning?

ASKER

I got a mssg:

Windows Resource Protection did not find any integrity violations.

Pls advise what is next.

Manjunath Sullad

Check CBS logs in below path,

%WinDir%\Logs\CBS\CBS.log.

and check whether you are getting any errror in log file.

Check "Cannot repair" - If you found any file like this, We need to replace that server with working server

ASKER

I did so, no errors of "Cannot repair" was found.

ASKER

I am wondering if i need to run something before upgrading win2008 to win2012.
such as adprep or something?
Is that for upgrades that are DC or DNS or DHCP or AD?

Manjunath Sullad

Which role this server is handling,

You need to perform upgrade based on different role,

Ex : for AD server and DHCP server, You need to follow different procedure.

I tried to install win2012 again but it failed with same dumb error mssg of registry data error

ASKER

this is a standalone server that only has one function.
It has a database of user collection data.
It is on the domain.
It is a VM machine.

We tried an inplace upgrade last week from Windows 2008 R2 to Windows 2012 Server, and it broke the server, and the resulting applications on the server, did not work, services would not restart.

Resulting in us rolling back the server, and we've decided not to short cut, of perform an inplace upgrade.

ASKER

Andrew,
did MS say wy such thing happened?
Was your application compatible with the new OS, Win2012?
Did you update/upgrade your app before install?

Did you get the same install complication as i am going through now?

Andrew Hancock (VMware vExpert PRO / EE Fellow/British Beekeeper)

Microsoft stated, this was to be expected if you have current applications installed.

The new application was compatible and tested with Windows 2012.

Yes, trashed the server and application.

I would therefore not recommended in-place upgrades. There is a warning to this, also when you perform an upgrade!

ASKER

I called MS Support and they said they can assist but I have to pay.
I think they do that on purpose.
I saw on a video of a user do a sysprep and something else, I wonder if that is for a standalone server or if it is for a DC or DNS?

What u think?

Andrew Hancock (VMware vExpert PRO / EE Fellow/British Beekeeper)

In-place upgrades are troublesome, it says as much, before you start the upgrade.

ASKER

looks like i have to on my contact the software manufacturer running on my win2008 machine on how to export all settings. thank you.

ASKER

I am going to make another attempt to do an in place upgrade.
This time I will use 'Easus Partition Master' to strip 100 MB off the C partition and then apply it to the E: partition to make it 200MB because all I had left was 4MB and Win2012 would not install because of lack of space on the E partition.
I will not defrag the E partition like last time.
When that is done then I will attempt to install Win2012.
I will post my findings when I am done.
