    What is mean "VMFS Resignaturing" ?

    MICDROP Novice

      Hi all,


      I planning upgrade esx 4.0 to esxi 6.7 ( maybe I should upgrade it through 5.5 .. )


      Because esx 4 uses VMFS3 and ESXi 6.7 not support VMFS 3, I must upgrade VMFS 3 to VMFS 5.


      I referred to this KB, and when I mount VMFS3 to ESXi, it is automatically upgraded to VMFS5.


      However, case of below, upgrade will be failed.

      • When you mount the VMFS3 datastore after its resignaturing, it does not upgrade to VMFS5. You must perform the upgrade manually.


      I will try to eliminate the possibility of an upgrade failure, but what does resignature mean?


      Will the VMFS 3 datastore be automatically upgraded to VMFS 5 when it is mounted on ESXi 5.5 or later?


      Thank you in advance for your advice.
