I followed instructions from the Move All Databases (SharePoint Server 2010) article.
I have a SQL alias set up on the original database server and the new database server. I can connect to the old server from the new server via SQL Server Management studio. The configuration in SQL Server Configuration Manager on both servers is as follows:
sqlAlias TCP/IP Oldserver
Named Pipes Enabled
SQL Server ServicesService Running Automatic Log On As
SQL Server Browser Yes Yes DOMAIN\SQLservice
SQL Server Yes Yes DOMAIN\SQLservice
SQL Server Agent Yes Yes DOMAIN\SQLservice
When I change both servers configuration by changing the alias to the new server, I cannot connect to the new server from the old server. All server security logins match in SQL Server Management Studio. I am able to ping the new server from the old server using both the IP and the SQL alias. What am I missing?
