How to Update to VMware ESXi 8.0.3j (25429389)

Written By Sebastian Sime (Super Administrator)

Updated at July 1st, 2026

→ Applies to: SynetoOS 4.x, SynetoOS 5.x and SynetoOS 6.x running VMware ESXi 7.0.3 (build 23307199) and above

The update requires the entire physical host to be rebooted

IMPORTANT
It is recommended to backup VMware ESXi configuration before performing the update ("How to Backup/Restore Host Configuration in VMware ESXi")

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

 

Step 1. Check your VMware license and proceed only if it's compliant with version 8.0

Step 2. Power-off all VMs including SynetoOS and Syneto File Recovery

Step 3. Save you configuration in a file before to upgrade the system (see this article)

Step 4. Connect to VMware ESXi CLI (via SSH)

Step 5. Move to your datastore deployment folder (replace <datastore> with your datastore/folder name)

cd /vmfs/volumes/<datastore>/deployment

EXAMPLE

cd /vmfs/volumes/datastore1/deployment

 

Step 6. Modify firewall rules to allow subsequent activities

esxcli network firewall ruleset set -e true -r httpClient

 

Step 7. Download Syneto VMware ESXi 8.0.3j (build 25429389)

wget -O esx-syneto-update.zip "https://storage.googleapis.com/syneto_public_files/updates/ESXi-Upgrade-Bundles/ESXi8/ESXi-8.0U3j-25429389-Syneto-v8.367-release.zip" --no-check-certificate

 

Step 8 (optional, for server Dell only). Enable kernel module

esxcli system module set --enabled=true --module=vmw_ahci

 

Step 9. Run the following command to remove unwanted VIB

esxcli software vib remove -n vmware-esx-sas3ircu

EXAMPLE OUTPUT

Removal Result
   Message: Operation finished successfully.
   Reboot Required: false
   VIBs Installed:
   VIBs Removed: LSI_bootbank_vmware-esx-sas3ircu_17.00.00.00-03
   VIBs Skipped:

 

Step 10. Run the following command to remove unwanted VIB

esxcli software vib remove -n lsiprovider

EXAMPLE OUTPUT

Removal Result
   Message: Operation finished successfully.
   Reboot Required: false
   VIBs Installed:
   VIBs Removed: LSI_bootbank_lsiprovider_500.04.V0.65-0005
   VIBs Skipped:

 

Step 11. Install the update (replace <datastore> with your datastore/folder name)


If you're updating from VMware ESXi 7.0.x:

esxcli software vib install -f -d /vmfs/volumes/<datastore>/deployment/esx-syneto-update.zip

EXAMPLE

esxcli software vib install -f -d /vmfs/volumes/datastore1/deployment/esx-syneto-update.zip

 

If you're updating from VMware ESXi 8.0.2 and above:

esxcli software profile update --depot=/vmfs/volumes/<datastore>/deployment/esx-syneto-update.zip --profile=ESXi-8.0U3j-25429389-Syneto-v8.367 --no-sig-check --force

EXAMPLE

esxcli software profile update --depot=/vmfs/volumes/datastore1/deployment/esx-syneto-update.zip --profile=ESXi-8.0U3j-25429389-Syneto-v8.367 --no-sig-check --force

 

If you're updating from VMware ESXi 8.0.2 or later and Legacy BIOS is active:

esxcli software profile update --depot=/vmfs/volumes/<datastore>/deployment/esx-syneto-update.zip --profile=ESXi-8.0U3j-25429389-Syneto-v8.367 --no-sig-check --force --no-hardware-warning

EXAMPLE

esxcli software profile update --depot=/vmfs/volumes/datastore1/deployment/esx-syneto-update.zip --profile=ESXi-8.0U3j-25429389-Syneto-v8.367 --no-sig-check --force --no-hardware-warning

 

Step 12 (optional). Check that no errors occur

If you receive this error:

[InstallationError]
[Errno 28] No space left on device
vibs = VMware_locker_tools-light_12.5.1.24649672-24723868
Please refer to the log file for more details.

Connect to VMware ESXi (via GUI), then enable SWAP memory:

 

Step 13 (optional). In case of error occurred at Step 14, install the update again (replace <datastore> with your datastore/folder name)


If you're updating from VMware ESXi 7.0.x:

esxcli software vib install -f -d /vmfs/volumes/<datastore>/deployment/esx-syneto-update.zip

EXAMPLE

esxcli software vib install -f -d /vmfs/volumes/datastore1/deployment/esx-syneto-update.zip


If you're updating from VMware ESXi 8.0.2 and above:

esxcli software profile update --depot=/vmfs/volumes/<datastore>/deployment/esx-syneto-update.zip --profile=ESXi-8.0U3j-25429389-Syneto-v8.367 --no-sig-check --force

EXAMPLE

esxcli software profile update --depot=/vmfs/volumes/datastore1/deployment/esx-syneto-update.zip --profile=ESXi-8.0U3j-25429389-Syneto-v8.367 --no-sig-check --force


If you're updating from VMware ESXi 8.0.2 and Legacy BIOS is active:

esxcli software profile update --depot=/vmfs/volumes/<datastore>/deployment/esx-syneto-update.zip --profile=ESXi-8.0U3j-25429389-Syneto-v8.367 --no-sig-check --force --no-hardware-warning

EXAMPLE

esxcli software profile update --depot=/vmfs/volumes/datastore1/deployment/esx-syneto-update.zip --profile=ESXi-8.0U3j-25429389-Syneto-v8.367 --no-sig-check --force --no-hardware-warning

 

Step 14. Verify updated version

Installation Result
	Message: The update completed successfully, but the system needs to be rebooted for the changes to be effective.
	Reboot Required: true

 

Step 15. Modify firewall rules to disable subsequent activities

esxcli network firewall ruleset set -e false -r httpClient

 

Step 16. Reboot the system

reboot

 

Step 17. Verify updated version after reboot

esxcli system version get
