Upgrading Hosts That Have Third-Party Custom VIBs

A host can have custom vSphere Installation Bundles (VIBs) installed, for example, third-party drivers or management agents.

When you upgrade an ESXi host to 7.0, all supported custom VIBs are migrated, regardless of whether the VIBs are included in the installer ISO. If the host or the installer ISO image contains a VIB that creates a conflict and prevents the upgrade, an error message identifies the VIB that created the conflict. To upgrade the host, take one of the following actions:

• Remove the VIB that created the conflict from the ESXi host and retry the upgrade. You can remove a VIB from the host by using esxcli commands. For more information, see Remove VIBs from a Host.
• Use the vSphere ESXi Image Builder CLI to create a custom installer ISO image that resolves the conflict. For more information about vSphere ESXi Image Builder CLI, see the vCenter Server Installation and Setup documentation.
