Hi Guys, a quick question
I'm rolling out 5 Exchange 2010 servers into a single Exchange 2003 environment next week. 2 Hub/CAS and 3 Mail servers and know the process to follow step-by-step to complete the server introduction for coexistence.
However, I have to present a risk and rollback plan if something goes wrong, but I cannot see through web research any issues that are likely to happen.
A couple of things to bear in mind is that there is no requirement for OWA or Active Sync services as this is an isolated site with a single Ex2003 server without any trimmings.
The 5 new Ex 2010 servers have been added to the domain and I am scheduled to install and configure Ex2010 next week.
What could go wrong and if so how would I roll back to the Single Ex2010 Server state?
In advance thank you for your advice.
