Can I upgrade from Windows Server 2003 STD to Windows Server 2003 R2 STD?

Hey there!  I have a client with a Dell PWR Edge server that has Server 2003 STD on it.  For a Medical Software upgrade, I need to go to Server 2003 R2 and more ram.  I assume that that upgrade is possible, yes?

Also it has 4 GB ram and I want to put 8GB, will R2 accept that?

perfect and the Ram question?
Depends on version?

Windows Server 2008 R2 Datacenter  -  2 TB
Windows Server 2008 R2 Enterprise  -  2 TB
Windows Server 2008 R2 for Itanium-Based Systems  -  2 TB
Windows Server 2008 R2 Foundation  -  8 GB
Windows Server 2008 R2 Standard  -  32 GB
Windows HPC Server 2008 R2  -  128 GB
Windows Web Server 2008 R2  -  32 GB

Create a reliable backup. Make sure you always have dependable copies of your data so you can restore your entire system or individual files.

Just saw you had put STD so that is fine with 8Gb.  Thats the max though.

You also do realise that R2 can only be used on 64 bit machines?


Ignore that last, thats for 2008!

2003 R2 is

Windows Server 2003 R2 Standard Edition  
4 GB Max on 32 bit
32 GB Max on 64 bit

Yes, you can upgrade to Windows Server 2003 R2.
You do not need to do the entire OS installation. There are two disks for Server 2003 R2. Disk 2 is for installing the R2 version. You can just install that and have it. A reboot is necessary.

As for the RAM:

Server 2003 x86 STD: 4 Gb
Server 2003 x86 Enterprise : 32 GB
and Data center : 64 Gb with PAE switch is what the max can be used.

Good Luck !!

Great! Thanks all! So if it's 32 bit now, then the r2 will only take 4gb ram? And I'd have to go to enterprise to get 8gb ram and stay on 32 bit?
Yes that's correct
