Problems to Update VMware ESXI Custom Cisco

[jorgeg83]

Hi there, 

I'm looking for a custom Cisco ISO of ESXi 6.7u3 or possibly version 7.0, as those versions are no longer available on Broadcom's site currently. I'm running VMware ESXi 6.7.0, build 10302608, and I want to upgrade to ESXi 8.0u3 custom Cisco. However, I'm not sure if a direct upgrade is possible or if I first need to upgrade to version 6.7u3 or 7.0 before moving to 8.0u3

I attempted to upgrade directly to 8.0u3, but it threw several errors. For example:

Unable to download VIB: This may be due to network problems or the specified VIB does Not exist or does Not have a proper 'read' privilege set. Make sure that the specified VIB exists and can be accessed from vCenter Server.

These VIBs on the host do not have the requiered SHA-256 checksum for their payloads: NetApp_bootbank_NetAppNasPlugin_1.1.2-3 Thiswill prevent VIB security verification and secure boot from functioning properly.

Please remove these VIBs and contact your vender for replacements.

Thanks!

Upgrading directly from ESXi 6.7.0 (build 10302608) to ESXi 8.0 Update 3 (8.0u3) is not supported as a direct in-place upgrade.

Here's why:

• VMware supports direct upgrades only from ESXi 7.0 and later to ESXi 8.x.

• ESXi 6.7 → 8.0 is not a supported direct upgrade path, even though the installer may technically allow it.

Recommended Upgrade Path:

To upgrade from ESXi 6.7.0 to 8.0u3, follow this two-step upgrade path:

1. Upgrade from ESXi 6.7.0 → ESXi 7.0 Update 3 (latest)

2. Then upgrade from ESXi 7.0u3 → ESXi 8.0u3

Hi Oliver, thank you for you answer. Do you know where I can download ESXi 7.0u3 Custom Cisco? In the Broadcom site this .iso is not available.

Thanks

Hi Jorge, i can give you a VMware-ESXi-7.0.3d-19482537-Custom-Cisco-4.2.2-a.iso.

We just need to agree, how to exchange

Could you upload it google drive?

On the other hand, my vCenter has been upgraded to version 8.0u3, so I shouldn't have any problems, right?

Thanks so much, Oliver! I'll try to install it, and if everything works fine, I'll close this post.
