First time using this resource so forgive me if I don’t know all the procedures.
I am installing Exchange 2010 in a 2003 environment, below is my 2003 server environment.
•“Email” – Clustered mailbox servers
•“OWA” – Client access
•“Exchange” – Public folders
•“Email01” - First 2010 CAS
I have done all the pre-prep work already (legacy, schema, AD prep), and started the installation of the first 2010 HUB/CAS server, I want to coexist the two environments for testing and later staged user migration (due to our size). I am at the part of when asked if this CAS will be internet facing, enter domain name … is this my “email.company.com” or our external URL “https://webmail.company.com/exchange?
Second, I am trying to understand the part about using legacy host name, and the coexistence of the two environments. My goal is to make sure external and internal user are not interrupted to how they access their email whether they are on 2003 or 2010 during the setup and testing.
I am reading the part about how to “Configuring CAS” and setup legacy name http://technet.microsoft.com/en-us/library/dd638130.aspx
, my question is that the steps in this article say to run these commands
•Enable-OutlookAnywhere -Server:<CAS2010> -ExternalHostName:mail.con
toso.com -SSLOffloading $false
•Set-OABVirtualDirectory <CAS2010>\OAB* -ExternalUrl https://mail.contoso.com/OAB
•Set-OwaVirtualDirectory <CAS2010>\OWA* -Exchange2003Url https://legacy.contoso.com/exchange
And so on.....
From what I understand is that I am using the same URL and hostname as in 2003, my concern is at any point in time well doing these changes will a user get redirected to 2010 and not see his mailbox because his mailbox still lives on 2003?
