i work for a chairty. We are a medium sized operation with around 800 members of staff. ICT Wise we have 8 servers, Main ones being 1 DC (HP Proliant ML370) 1 Exchange Server & 1 DC Replication server. These along with the other 5 servers all run some variant of Windows Server 2003. Recently we had our Exchang server go down and (With a lot of help from Experts Exchange! THANKS!) we managed to get it running again. However it is an old warhorse of a server that needs upgrading. Here is where we need some advice. Way I see it we have 3 options:
Upgrade Exchange to better Physical server but just keep it as 2003 server. Problem here is in 1 years time our DC is going to need upgrading, therefore making an upgrade now counter productive? (Am I right?) Other end of the spectrum we could go all out and replace the DC with a nice shiny new one and Exch. But THEN we have to decide to we go server 2008 or stay server 2003? I hope this makes sense! Obviously as a chairty we have a very limited budget and can only really make descisions like this once every couple of years, so we need to make sure it is the right one. So any advice guys?
What would you do?
What is the ideal situation?
How good is Exch 2007/Server 2008?
How interoperable is it with Server 2003?
Any other advice?
Anything we need to bare in mind when making these descisions?
Thankyou so much in advance!
