VMFS Version Recommendations

Everpure recommends using the latest supported version of VMFS that is permitted by your ESXi host.

For ESXi 5.x through 6.0, use VMFS-5. For ESXi 6.5 and later it is highly recommended to use VMFS-6. It should be noted that VMFS-6 is not the default option for ESXi 6.5, so be careful to choose the correct version when creating new VMFS datastores in ESXi 6.5.

Example of VMFS-6 in ESXi 6.5:

When upgrading to ESXi 6.5, there is no in-place upgrade path from VMFS-5 to VMFS-6. Therefore, it is recommended to create a new volume entirely, format it as VMFS-6, and then Storage vMotion all virtual machines from the old VMFS-5 datastore to the new VMFS-6 datastore. Once the migration is completed you can then delete and remove the VMFS-5 datastore from the ESXi host and FlashArray.
