This is the question a client of ours is asking. For now I have given a generic response that we will support this however they should provide us with a test environment.
Our application is using .net and we allow clients to configure our server service with the database instance name and username/password (we use sql-server authentication).
From what I understand all they will need to do is configure our application with the cluster instance name instead of the hostname of the database server. Reading the Prerequisites that Microsoft provide it seems like it will be completely transparent for us.
Is this correct? Are there other changes we need to make to our connection string? Any other gotchas?
