Windows 2003 DC " Can I add a windpws 2008 DC to the extiguish DC 2003 R2"
Posted on 2009-12-29
Here you go my question.
I am running a VM Ware ESX3i Version 4 64 bit. I just upgraded the Hardware and installed this new version of VMware.
I transferred back all my VM that are all 32 bit to this VM Ware ESX3i 64 Version 4.
My virtual environment is composed from 5 VM 32 bit.
1) Two DC windows server 2003 R2
2) One Exchange Server 2003 Windows 2003 R2
3) One File Server Windows 2003 R2
4) One backup Server windows 2003 R2
Now I want to add Two additional DC but on Windows Server 2008 64bit version. Once I do so, I want to remove the old DC 2003 and raise the level to windows 2008. Can I do so like this or I have to upgrade the DC to windows to 2008?
I want to do the same wiith the fileserver and with the Exchange.
Regarding the file server should be easy just install a new fresh windows 2008 and make it as file server, regarding exchange I want to install a new windows server 2008 64 bit and install exchange 2007 than transfer all the mail box from the 2003 to the 2007.
It seems to be easy but practically it's not that easy.
What you would advice as best practice?
It is better upgrade the DC 2003 R2 or installed an new and join it to the extinguish 2003 domain.
Do I need to extend the schema? Please could suggest a complete best practice for this new environment?
I already have an Idea on how to do so but I do not feel so secure.
Thanks in advances
