Hi anyone,I have this problem encounter doing inplace upgrade, i cannot proceed

:)

 

Is it possible to upgrade Windows 10 to Server 2012 R2?


No. Windows Server 2012 R2 is the server version of Windows 8.1

The server version of Windows 10 has not yet been released, but it will be called Windows Server 2016.

And no, you cannot upgrade a desktop OS to a Server OS.

 

Questions about Windows Server 2016 and 2012 R2

Hey guys, hopefully this is the right section to post my question in. I'm looking at helping out a friend who is working on a server solution for his small business (about 25 employees). He is currently looking at a Dell PowerEdge T430 server, and I am trying to come up with an alternative that doesn't cost like $4000 USD. It seems that Windows Server 2016 charges by Cores and CALs? What are CALs? We're looking to install it onto bare-metal, meaning it's not running in a VM, windows server is going to be installed directly onto it. I was also looking at Windows Server 2012 R2 because it seems a lot cheaper and doesn't do stupid shit like charging per core. Is Windows Server 2012 R2 still a decent option?

I think his main goal is to have people log onto the server as a domain and share files off of it, and save his archives to it. This was going to be my recommended build:
System Builder

Again, I'm trying to figure out about Windows Server 2016 vs 2012 R2 and what version of 2016 to get if he decides to go that route. For a raid card since I want to be running those two 6tb hitachi drives in raid 1, I figured something like this LSI card would suffice:

Any thoughts and suggestions? Really could use help with the OS side of things, I think that the hardware I selected is pretty good. I already have a HAF X case I'd just throw in for like $100, which will suffice for a case. Thanks for all your guys' thoughts and suggestions.

Edit: Just to explain why I am so desperately trying to help him get away from Dell, I took a screenshot of the hard drive selection for the customizing Dell Server. They want $163.17 USD per 1TB 7.2K RPM Sata Drive, which is not just ridiculous but it's highway robbery.

 

Convert Windows Server 2012 R2 Evaluation to Windows Server 2012 R2

I have purchased the product key of Windows Server 2012 R2. Now the server is on Windows Server 2012 R2 Evaluation. I found a few links there they explained on how to convert from Windows Server 2012 R2 Evaluation to Windows Server 2012 R2 with valid product
key. One of the example is this link:

How to activate Windows Server 2012 R2 Evaluation - Nicolas Ignoto, CTP

Is this a correct way to do? If I follow this step, will my data be erased?

I want to avoid formatting/fresh Windows install because there are some software in the server that we do not know how to backup. We just want to get it activated now, backup will be sorted out later.
