I am working on building a new mail server with E2010SP1, but before I can start the exchange install, I need to extend the schema. To safeguard our environment from a bad schema extension, it is my intention to use the repadmin /options (servername) +disable_outbound_repl command on our DC/schema master, extend the schema, and then re-enable replication once I am able to confirm that the extension went off without any major issues.
The only problem is that our DC/schema master is a x32-bit platform... and the E2010SP1 installer is x64-bit and therefore won't allow me to run it directly on the DC.
I *could* run the schema extension from my PC, which is x64-bit, but -- and correct me if I'm wrong -- I'm fairly certain that doing so would apply across all of our DCs... not just to the DC/Schema Master with replication disabled. So, in that case, if something were to go awry, we'd be looking at a complete forest rebuild (something I'd much rather avoid...)
So here's a description of our DC environment. Please let me know if there is a good way to approach this. I don't think there is a E2010SP1 installer in the x32-bit variety.
Domain Controller/Schema Master - Windows Server 2008,x32-bit.
Exchange Server (Also DC) - Windows Server 2003 x64-bit (yes, I know... this is exactly what I"m trying to get rid of. Been here for 9 months and had more than one 2003 server in the environment... been trying to decommission them and get everything up to date)
