Upgrading or Reinstalling VMware Components (VMware Environments Only)
Prior to installation or upgrade, see VMware documentation for complete information regarding installation and upgrading of VMware products.
Before beginning the installation or upgrade, verify that your version of Zerto supports the new VMware version.
See the Zerto Virtual Replication Interoperability Matrix for the list of VMware environments supported by this version of Zerto.
See the following sections:
Upgrading a vCenter Server
|
•
|
Zerto recommends that you upgrade a vCenter Server rather than reinstalling it. |
|
•
|
When upgrading both vCenter and an ESX/ESXi, you must first upgrade the vCenter. |
|
•
|
Zerto components are not affected by a vCenter Server upgrade. Protection continues and no additional procedures are required. |
|
•
|
When upgrading a vCenter Server, make sure that you preserve thevCenter database. Preserving the existing database is required in order to continue using the existing Zerto installation. |
|
Note:
|
If the recovery vCenter Server service is stopped, recovery operations are not possible until the service is restarted. |
|
•
|
When upgrading a vCenter Server make sure to close the ZVM UI. |
Reinstalling a vCenter Server
If you need to reinstall the vCenter Server, including rebuilding the database, contact Zerto support for help throughout the re-installation.
Upgrading vCloud Director
|
•
|
Zerto recommends that you upgrade vCD rather than reinstalling it. |
|
•
|
Zerto components are not affected by a vCD upgrade. Protection continues, and no additional procedures are required. |
|
•
|
When upgrading vCD from version 1.5, to 5.1 or higher, you must change the storage profile for each protected virtual machine from * (any) to a valid storage profile to use for that virtual machine. Contact Zerto support for help with the upgrade of VPGs. |
|
•
|
If you need to reinstall vCloud Director, contact Zerto support for help throughout the re-installation. |
Upgrading VMware Tools
You do not need to upgrade VMware Tools on a VRA.
Upgrading or Reinstalling a Host
When upgrading both vCenter and an ESX/ESXi, you must first upgrade the vCenter.
When upgrading, including applying patches, or reinstalling a host with an active VRA:
|
1.
|
First change the recovery host of every virtual machine in every VPG that recovers to this host, to avoid a Delta Sync after the host has been upgraded and the VRA started up. |
|
2.
|
Then upgrade the host. You can move the virtual machines to a different host from within the Zerto User Interface, as described below, or by using cmdlets, as described in Zerto Virtual Replication PowerShell Cmdlets Guide. |
Use the following procedure.
To change a recovery VRA:
|
1.
|
In the Zerto User Interface, click SETUP > VRAs. |
|
2.
|
Select the VRA to change and click MORE > Change VM Recovery VRA. |
The Change VM Recovery VRA dialog is displayed, listing all the virtual machines being recovered on that host.
|
3.
|
Review the list and select the virtual machines to change the target host to another specified target host. |
|
4.
|
From the Select the replacement host drop-down list, select the target host for these virtual machines. |
You can move some virtual machines to one replacement target host, and then by repeating the operation, you can move other virtual machines to a different target host.
|
•
|
Validation is performed to make sure the selected target host can be used. For example, the datastores used by both the VRAs are accessible from both hosts. |
|
•
|
Any implications of the change, such as whether synchronization might be required after the change is also displayed. |
|
•
|
During this procedure you cannot edit the affected VPGs nor attempt a failover, move, failover test, or clone operation. |
|
•
|
At the end of the procedure a Bitmap Sync might be required to resynchronize the protected machines with the recovery VRAs. |
|
6.
|
VRAs installed using a password to access the host, that require the password to be updated, for example, when the host is upgraded, must be updated with the new password. |
To do this, see the following procedure.
To change the host password required by a VRA:
|
1.
|
In the Zerto User Interface, click SETUP > VRAs. |
|
2.
|
Select the VRAs that need to be updated and click MORE > Change Host Password. |
The Change Host Password VRA dialog is displayed.
|
3.
|
To change the connection method or host password, do one of the following: |
|
•
|
If the VRA is using a password to connect to the host and should use vSphere Installation Bundle, VIB, deselect Use credentials to connect to host. |
|
•
|
If the VRA is using VIB to connect to the host and should use a password, select Use credentials to connect to host and enter the password. To display the password in plain text, click in the box next to the field. |
|
•
|
If the VRA is connecting to the host with a password and the password for the host has changed, enter the new password. To display the password in plain text, click in the box next to the field. |
