I used this site to prepare and do the exchange migration.
Migrating a small organization from Exchange 2010 to Exchange 2016 (Part 1) - TechGenix
after step 4 : Updating Exchange 2010 Virtual Directory URLs : Enable-OutlookAnywhere -Server $Server -ClientAuthenticationMetho
d Basic -SSLOffloading $False -ExternalHostName $HTTPS_FQDN -IISAuthenticationMethods NTLM, Basic
If first receive an error that the RPC connection allready exists.
and after updating the DNS records from mail.
I am unable to get the Outlook clients connected to the new mailserver 2016. it constantly asks for credentials and is unable to start outlook.
I think this can also be because the first IT provider has called the exchange 2010 server “mail”.
after changing the A records Mail. the new 2016 server loses connection with 2010.
any tips? can i rename the old server without any problems? so i can easily change the A record?
