VMWARE ESXI 6.7 INCREASE FILE SYSTEM UPGRADE
The most time-consuming part is lates part of ugrade… you cannot upgrade VMFS 5.xx directly to VMFS 6, so you need migrate all VMs from datastore to the temporary datastore, unmount and remove old VMFS 5.xx datastore, create a new, format it as VMFS 6 and migrate all VMs back from temporary datastore. The scenario is the same for each customer – upgrade VCSA, firmware on hosts, ESXi nodes and upgrade VMFS to latest 6.0, which was introduced with vSphere 6.5. I going through doing some upgrade of VMFS5.xx to VMFS6 on the customers datastores. VMware – Can’t unmount/remove datastore – in use or file system is busy
