Upgrade From Windows 2012 to Windows 2012 R2

Dear EE,

I have purchased Windows 2012 Standard Edition License for my company.

Now i came to know that we should purchase Windows 2012 R2 instead of Windows 2012.

Please help me to following queries i will be great-full to you.

1) Do we need to PAY MORE ($) for Windows 2012 R2 Standard Edition. (We have License of Windows 2012 Standard Edition).

2) How can we upgrade Windows 2012 Standard Edition to R2 with out taking any BACKUP of Server.

3) Can you please share the steps to upgrade Windows 2012 to R2.

Thanks

Simplify Active Directory Administration

Administration of Active Directory does not have to be hard.  Too often what should be a simple task is made more difficult than it needs to be.The solution?  Hyena from SystemTools Software.  With ease-of-use as well as powerful importing and bulk updating capabilities.

2) How can we upgrade Windows 2012 Standard Edition to R2 with out taking any BACKUP of Server.
Depends upon the ROLES installed if not a DC then an inplace update is possible.  You should ALWAYS have lots of backups.

Dear David,

Thanks for your reply.

1) Can you please confirm me how much i need to pay for R2.
2) 2012 OS is installed on IIS (Web Server) and not on AD or DC. Please confirm can i make INPLACE UPDATE with out taking BACKUP in PRODUCTION. Is it safe.

Thanks

$862 plus CALS per every 2 physical CPU's

only a web server you can do an inplace.. don't know why you'd want to upgrade as IIS didn't change all that much in the R2 version.
