    - HYPER Appliances running SynetoOS 4.x ONLY

    - VMware ESXi 7.0U3 and above

This guide describes how to upgrade your Syneto VMware ESXi to version ESXi-8.0U2

  • Check your VMware license before upgrade and proceed only if it's compliant with version 8.0
  • Power-off all VMs including Syneto OS and Syneto File Recovery
  • Save you configuration in a file before to upgrade the system by following this tutorial.


  • Reverting to a previous build does not revert the tools-light vib version installed on the ESXI host
  • Rolling from ESXi 8.0 to 7.0 is acceptable, as there are no partition changes between the two versions.

The upgrade requires the host to be rebooted.

1. Open SSH connection to Syneto ESXi

2. Change directory to your datastore deployment folder (name may vary)

cd /vmfs/volumes/datastore1/deployment

3. Modify firewall rules to be able to download the upgrade bundle

esxcli network firewall ruleset set -e true -r httpClient

4. Download Syneto VMware ESXi 8.0U2

wget -O --no-check-cert

You can also use http instead of https for download link. E.g.****

Make sure there're no firewall rules or antivirus blocking the connection.
Download MD5 Checksum

5. Update

esxcli software vib install -f -d /vmfs/volumes/datastore1/deployment/

Check installation status:
