Restore to Different VMware Version

  • Posted on behalf of Casey S.

    Is it possible to replicate using Zerto between two VMware hosts that are on different versions? I want to replicate between a VMware 5.5 Host and a VMware 6.7 Host.

    Hello Casey,

    Mike from Zerto here.

    Yes, replication between hosts on different ESXi versions is indeed supported.

    thanks for the information

    Hi,

    I know I am a little late for the party but I just wanted to add to this question:

    1. would it be possible to replicate from higher to lower version of ESXi, ie. 7.0 to 6.5?
    2. are there any limitations in doing that? Let’s say to keep VM hardware version 13 (as supported by the lower version of ESXi hosts) or any other limitations?

    Thanks,

    Robert

    Hi Robert

    The VM hardware version would need to be compatible on the destination of where you are replicating to.

    Hi,

    This is Kalsang from Zerto.

    The following conversions are done to a protected virtual machine when it is recovered in the vCenter Server:
    • Virtual machines are recovered in vCenter Server with the highest hardware version supported by the vCenter Server host version under which the virtual machine is recovered.
    • A Generation 1 (Hyper-V) virtual machine is recovered in vCenter Server with BIOS with the highest supported hardware version.
    • A Generation 2 (Hyper-V) virtual machine is recovered in vCenter Server with EUFI. The host in vCenter must support hardware version 8 or higher.

    Review the following VMware KBs to determine the highest version of the vCenter/ESXi host version

    https://kb.vmware.com/s/article/2007240

    https://kb.vmware.com/s/article/1003746
    Depending on the highest version reported on the VMware KB, upgrade Zerto to the minimum version of the supported VM hardware version.
    For example:</p>
    ESXi 6.7 U2 supports up to VM Hardware version 15.
    Our interoperability guide indicates that it is supported from Zerto 6.5U4P1 and Zerto 7.0U2P2 in their respective version families, therefore if below those versions, upgrade Zerto.
    If the recovery hosts are at different ESXi versions and you receive an alert from Zerto and/or vCenter, then you can perform one of the following:
    a. Upgrade the recovery host to a version that supports the protected virtual machine hardware version.
    b. Change the recovery host to one that supports the protected virtual machine hardware version.

    Hope that helps.

    Best regards,
