What kind of down time will I have Clustering my Exchange 2003 Enterprise Server ?   

Hello

I upgraded to a new Exchange 2007 Enterprise server at the main office. Now
my CIO wants me to setup a another Excahnge 2007 Enterprise Server at a COLO
as a cluster for failover if the Exchange 2007 Server at the Main office has
a power outage or network outage.
When I set this server up as a cluster node A with the the new Windows 2003
R2 Server for node B, What kind downtime will I have, should I doit after
hours ?

Thanks
Tony

- Assuming you want to implement either CCR or SCC cluster-- you can't add 
an existing Exchange Server to a cluster (or create a new cluster from an 
existing server) without removing Exchange Server 2007.
- The recommended solution for site resilience is SCR. You can use SCR with 
clustered/non-clustered source Exchange servers, and replicate Storage 
Groups to clustered/non-clustered (SCR) targets. This does not involve any 
down time.
- However, SCR does not provide "failover" from source to target, unlike 
clusters. SCR targets need to be activated manually. Generally speaking, 
it's a good idea to have manual intervention and let an administrator decide 
to activate a remote site/server. If that's your goal, SCR will work.
- If not, and you're considering setting up CCR - using Windows Server 2008 
Failover Clustering is recommended because of its ability to span IP 
subnets. (Both subnets have to be associated with the same AD Site).
