When you upgrade the file service, the upgrade is performed on a rolling basis. During the upgrade, the file server containers running on the virtual machines which are undergoing upgrade fails over to other virtual machines. The file shares remain accessible during the upgrade. During the upgrade, you might experience some interruptions while accessing the file shares.


Ensure that the following are upgraded:
  • ESXi Hosts
  • vCenter Server
  • vSAN disk format


  1. Navigate to the vSAN cluster and then click Configure > vSAN > Services.
  2. Under vSAN Services, on the File Service row, click CHECK UPGRADE.
  3. In the Upgrade File Service dialog box, select one of the following deployment options and then click UPGRADE.
