Great to hear. Any challenges or questions related to it?

No issues-just took a bit of time to manually run through each VM after performing an inventory of the VMs that had Secure Boot enabled (we skipped the ones that did not). ProxMox was much easier to update the certificate with two mouse clicks for each VM.

For vSphere VMs, we recommend using automated methods to update the certificates. Please refer to https://knowledge.broadcom.com/external/article/423893/secure-boot-certificate-expirations-and.html.
The manual method documented in https://knowledge.broadcom.com/external/article/423919/manual-update-of-secure-boot-variables-i.html should be used as a last resort.
