Hybrid environments deployment
When you deploy the hotfixes to a hybrid environment (Such as AlwaysOn, replication, cluster, mirroring, and cluster), we recommend that you go and refer to the following articles before you deploy them:
- SQL Server failover cluster rolling update and service pack process.
If you do not want to use the rolling update process, follow these steps in order to apply a CU or SP:
- Install the service pack on the passive node.
- Install the service pack on the active node (This step requests service restart).
- Upgrade and update of availability group servers that use minimal downtime and data loss.
If you enabled AlwaysOn with SSISDB catalog for additional considerations about how to apply a CU or SP in these environments, see the information about SSIS with AlwaysOn.
