Dear Sir,

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...???

Thank You.

This is a good reference:  http://msdn.microsoft.com/en-us/library/ms191295.aspx#BestPractices

See the 'Important' section, where it says you must start with the passive node first.  Definitely read the 'Best Practices Before Upgrading a SQL Server Failover Cluster', and then see the detailed steps 'To upgrade a SQL Server failover cluster'.

I had a cluster that had four SQL instances and a Sybase in the cluster. Three of the SQL clusters were standard. The fourth was a SQL Express.

Connect to the instance and do a "select @@Version" to make sure it is not an Express instance.

Hello dbaSQL,

In fact, I follow MS Best Practice article without success.

I am not able to select any instance to upgrade during the migration process from SQL 2005 cluter to SQL 2008 R2.

I have 2 identical Dell Servers and SCSI PowerVault.
2 Network cards each, one public and one private between 2 nodes for hearbeat set to 10MB speed.

Really strange, the failover is working good on SQL 2005.
The problem I cannot upgrade...

Any help?

Thanks.

Back in 2005 -- You could only install the instance from the Active cluster -- and all the rest of the instances had to be on the active cluster. No 50-50.

When doing SPs -- you had to do it from the inactive cluster, with the rest of the nodes on the active node.

In SQL2005 if you had MyClusterName\Instance1 and MyClusterName\Instance2, etc. to install MyClusterName\Instance5 you had to move all nodes to MyClusterNode1 and install the Instance5 from there.

But when you install a SQL service pack you had to move the InstanceX to a single node (MyClusterNode1) snd then install the the SP from MyClusterNode2...

Thank you Jimpen for the reply.

In fact, I am doing SQL Server migration from 2005 to 2008 R2.
I am not installing a new SQL instance...
The problem is that during the upgrade process, my current SQL instance is not showing to perform an in-place upgrade...

Any help.

Thanks.

Hey, this is a very good read by Denny Cherry:
http://www.windowsitpro.com/article/clustering/upgrading-a-sql-server-2005-cluster-to-a-sql-server-2008/2.aspx

See page 2, about 3/4 of the way down, the paragraph that begins with 'Next, the installer will run another set of checks.'
You will see the default instance shown first, and it says that if you have multiple instances, each one will need to be upgraded independently of the others.

Do you have the option to select different instances at this step in the upgrade?
