About applying updates to Resiliency Platform
Updates to Veritas Resiliency Platform provide significant benefits, such as improved functionality, performance, security, and reliability.
Updating the Resiliency Platform (Resiliency Manager and IMS) involves saving configuration to the data disk of the previous version appliance and then attaching the data disk to a new, freshly deployed virtual appliance.

In Veritas Resiliency Platform, you can apply updates to the following:
Veritas Resiliency Platform virtual appliance
Veritas Resiliency Platform add-ons
Host packages on the assets that are added to the Infrastructure Management Server (IMS) as a host
Veritas Replication VIB
Veritas Resiliency Platform 10.2 is the minimum version supported for upgrade to version 10.4. If your installed version is older than minimum supported version, then you should first upgrade to your supported upgrade version.
Appliances should be upgraded in following sequence:
All Resiliency Manager appliances
All IMS appliances
All Replication Gateway appliances
All managed hosts
Table: Upgrade path for Veritas Resiliency Platform 10.4
Current version | Can upgrade to |
|---|---|
v10.2.0.0 | v10.4 |
v10.3.0.0 | v10.4 |
Following are some considerations for applying update to the Resiliency Platform components:
The minimum version of the virtual appliances should be 10.1 or 10.2 to upgrade to Resiliency Platform 10.4.
You must apply the updates on Resiliency Manager and IMS to take the complete advantage of the changes available in the updates. You need to replace the Replication Gateway to reflect the new upgrade changes in version 10.4.
Ensure that no workflow or resiliency plans are running in the background.
After applying updates, you can access the Resiliency Manager web user interface through the NIC that is used for communication with other Resiliency Manager.
You can change the NICs that are used to access product user interface. Use network > nic-for-UI Klish command to add additional existing configured NICs for UI access.
A pre-upgrade checklist is integrated with the prepare-for-update command to validate the virtual appliance. This checklist is applicable to Resiliency Manager only. For more details, refer Pre-upgrade checklist
The Resiliency Platform upgrade process is divided into 3 main parts. The upgrade process is applicable for the following platforms:
Upgrading Resiliency Platform in AWS environment
Upgrading Resiliency Platform in Azure environment
Upgrading Resiliency Platform in VMware environment
Upgrading Resiliency Platform in Hyper-V environment
The detail steps are mentioned according to the respective topics based on the environments. The high level overview of the process for applying updates to the virtual appliances of the Resiliency Platform in version 10.4 is mentioned below:
Using KLISH commands, prepare the virtual appliances for upgrade.
Detach the data disk of the existing virtual appliance and attach the data disk of the virtual appliance to the new 10.4 appliance.
Boot the virtual appliance to start the automatic bootstrap process based on the environment you want to upgrade.
In case of Replication Gateway upgrade, you need to replace the existing Replication Gateway with the newer version Replication Gateway.
Before applying updates, ensure that you have performed pre-upgrade tasks for specific scenarios:
See Pre-upgrade tasks.
The following table consists of the topics you need to refer to the steps mentioned above for applying updates in Veritas Resiliency Platform:
Table: Applying updates to Resiliency Platform
Step | Task | Steps to perform the task |
|---|---|---|
1 | Prepare for update using Klish commands. Prepare the virtual appliances for update using Klish commands. | |
2 | Detach / attach data disk. You need to perform following steps:
Choose the environment from the list on which you wish to upgrade the Resiliency Platform. | Step 2: Upgrading the Resiliency Platform (Detach / attach the disk) |
3 | Start Automatic bootstrap process. After the bootstrap process is complete, the upgrade process should automatically start. | |
4 | Replace the Replication Gateway appliance | Steps to replace the Replication Gateway appliance For modifying the encryption: |
5 | Apply update to the single or multiple Resiliency Managers in a domain. In case of multiple Resiliency Managers in the domain, the update needs to be applied on all the Resiliency Managers in synchronization. Note that if you apply update to the Resiliency Manager, then you must apply update to the IMS as well. If you do not update the IMS, the IMS stops data reporting to the Resiliency Manager. |
Apart from upgrading the Resiliency Platform virtual appliances, you need to update following other components too:
Table: Applying updates to other components of Resiliency Platform
Task | Steps to perform the task |
|---|---|
Apply update on the host packages. You must apply update to the Control Host after you apply update to the IMS. | |
Apply update on the InfoScale environment In case of InfoScale environment, apply update to the add-on. | Applying upgrade to Resiliency Platform for managing InfoScale clusters |
Upgrading the Veritas Replication VIB In case of recovery of VMware virtual machines to on-premises data center using Resiliency Platform Data Mover, If you had configured a resiliency group before applying update to IMS, you need to apply update to the Data Mover bundle. | |
Applying updates to the Veritas Data Gateway |
You also have an option of applying a private hotfix, if Veritas support provides you one.
