I would like to upgrade the underlying Operating System of our ZVM and I need to clarify some details beforehand.
During the upgrade reboots of the OS are needed – does it have an impact of the site replication process?
Is the ZVM responsible for management and configuration or is it one of the core components of the Zerto environment?
In other words – is the site replication during the downtime of the ZVM still working or is the site replication interrupted during the downtime ?
Will the replication resume automatically if it is interrupted or are manual actions needed?
I would like to run the Setup.exe right out of the Windows_2019_ISO and I assume that this will not cause any problems for our Zerto installation?!
Do I need to stop the Zerto services before upgrading? We will set a VMware snapshot before performing the upgrade but do you suggest a backup of the Zerto database?
Do you have a best practice guide?
I guess upgrading from W2012R2_Std to W2019_Datacenter is supported?
Zerto Version 7.0 Build 070005867
Windows Server 2012R2 Standard /EN-US
Windows Server 2019 Datacenter /EN-USBrian SOctober 16, 2019 11:49:05 AM
Brian from Zerto here.
Basically, you can fo ahead and upgrade the ZVM OS, there is no need to stop services or anything, but replication will be down for the time of the upgrade, and, recovery is not possible until the upgrade is complete.
- Please refer to our KB ‘Upgrading guest OS of the ZVM VM machine’:
- I believe both Windows versions are supported for Zerto 7.0, Please refer to our Interoperability Matrix:
- Taking a snapshot of the ZVM before upgrading is a great idea, just in case the upgrade fails.
Let us know if it was helpful!Steffen WOctober 17, 2019 10:49:26 AM
Thanks for you reply. Upgrading to W2019 was deleting my ZVM Settings – the ZVM service was stopped too.
I rolled back to my VM snapshot.
How can I backup my ZVM Settings? Is Zerto Diagnostics the appropiate tool for doing so or is it just backing up my VPG Settings?
Kind Regards.Steffen WOctober 17, 2019 11:25:07 AM
Another unsuccessful attempt.
I exported the VPG Settings (Zerto diagnostics) and tried importing them after running the Windows Upgrade.
How can backup ALL ZVM Settings?Brian SOctober 17, 2019 11:26:28 AM
Sorry to hear that, if you would like us to investigate the issue, kindly open a case for Zerto Support.
Your statement is correct, using the Zerto diagnostic tool is only for VPG settings, meaning, that after the upgrade you will have to pair the sites, install VRAs and then import the VPG settings.

in the same boat here Windows 2008 R2 SP1 to Windos 2012 R2 no way to fix the issue
After OS Windows in place upgrade Zerto service is down and DB, when opening Zerto Diagnostics it ask for .Net Framework 4.5.2 and I installed that manually now Zerto Diag opens but all info in blank so I fill all and reconfigure same issue services not starting and I open again Zerto Diag all is blank even when the reconfigured was successful ….
so I applied all windows 2012 R2 updates which add tons of updates reboot server and all Zerto services are up but ZVM service wont’ start, Zerto Config is blank.
I tried a ZVM 6.5 Repair and that won’t help even when it finish OK
I tried a ZVM 7.0 and validation is all wrong and won’t let me try the upgrade
so far it’s not that simple as mention here which I found until now
I wanted to avoid opening a ticket with support since I am just doing a lab before upgrading my real ZVM server and I wanted to minimize the impact for my DraaS service for my customers but right now reinstalling and talking with 6 customer would be the way maybe
anyway maybe it’s simple and support can fix it in just one call, I am going to try next week
