Due to the technical conditions of the customer, a direct migration from the existing cluster to the new cluster is not possible. For this reason, a node of the existing cluster is removed during this migration, a local SQL server is created on it and the original SQL server on the cluster is migrated to this local SQL server. This in the form of a pre-migration. Then the new cluster is created and the databases of the local SQL Server are migrated to this cluster. The reason for this procedure lies in the use of SUN, which is decisive in ensuring that the old cluster environment can no longer be accessed after the migration of the cluster..
- Premigration of the database server on the cluster to a local installation.
- Creation of the new cluster.
- Migration of the local installation of the database server to the new cluster.
