SQL Server Instanse is not appearing during SQL Cluster Upgrade from 2005 to 2008 R2?
Posted on 2011-02-27
I'm facing the following problem during the migration process from SQL 2005 to 2008 R2 (Cluster).
I have two identical hardware, Win 2003 Server R2 Entreprise edition configured as Cluster active/passive for SQL 2005 Entreprise Edition.
Everything is working well, and the failover cluster is working pretty good.
Now, we are upgrading from SQL 2005 to 2008 R2, I started migrating the active SQL server instance from 2005 to 2008 R2, but during the wizard, SQL instance is not showing to continue the migration...
I tried to start the upgrade process from the passive server, without success as well...
The SQL instance is not showing...
All SQL 2008 R2 prerequisites are installed during the setup...
However, I upgraded many different Standalone SQL server instances and SQL mirroring without any problem.
Please I need help on how to upgrade from SQL 2005 to 2008 R2 without removing the cluster...???
