Issue/Introduction
Resolution
Points to remember:
- The upgrade of a distributed switch causes the hosts and virtual machines attached to the switch to experience a brief downtime. Please perform the activity during your maintenance window.
- Note:
- To be able to restore the connectivity of the virtual machines and VMkernel adapters if the upgrade fails, back up the configuration of the distributed switch.
- Refer this document to backup the DVS: https://techdocs.broadcom.com/us/en/vmware-cis/vsphere/vsphere/7-0/vsphere-networking-7-0/networking-backup-and-restore/exporting-importing-and-restoring-vsphere-distributed-switch-configurations.html
- If the upgrade is not successful, to recreate the switch with its port groups and connected hosts, you can import the switch configuration file.
- Export vSphere Distributed Switch Configurations
- Import a vSphere Distributed Switch Configuration
- Restore a vSphere Distributed Switch Configuration
- Note:
- If your current VDS version is 6.5, then you might experience a brief downtime while upgrading your switches to a later version.
- This link explains the known issues while upgrading from DVS version 6.5 to a later version: https://knowledge.broadcom.com/external/article/324546/upgrading-to-dvs-66-known-issues.html
- We also have a KB which briefs about Packet drops on VMs during DVS upgrade from 6.5 to 7.0.3.Refer to this link below:
- https://knowledge.broadcom.com/external/article/375040/packet-drops-on-vms-during-dvs-upgrade-f.html
- If your current VDS version is 6.6 or later, then you might not experience any downtime while upgrading the switches to a later version.
- Caution: After you upgrade the vSphere Distributed Switch, you cannot revert it to an earlier version. You also cannot add ESXi hosts that are running an earlier version than the new version of the switch
