I have a question.
I am planning to migrate from our current Exchange 2007 to 2010 the day after Christmas.
Our current Exchange is a Vsphere 5.1 virtual.
The new Exchange 2010 server is 2008 R2 Vsphere 5.1 Virtual as well.
We are currently running Exchange Server 2007 sp3 which this service pack, I understand did a lot of prep work to the schema for 2010.
My question is, the new server is up and I would like to go ahead and install Exchange 2010, get a lot of it configured so that I have time to test and see performance not just in exchange but on the vm itself with the rest of our environment which is mostly virtual. I just won't change DNS, MX or any other records until I am ready to migrate and know that it's stable.
Is there any problem in preparing our schema this far in advance for 2010? Will effect the functionality of our current 2007 exchange? I originally planned for a co-existence so I am thinking there is not much problem with this but my boss does not want to do the full switch over yet until we know the server is stable and I now agree with this.
Please let me know your thoughts, I just want to make sure.
