We are planning to upgrade our host for 6.0U2 to 6.5 U3 Do we need to do anything with zerto before/during or after the upgrade?
Please check the support matrix below. ESXi 6.5u3 is only supported by Zerto 6.5u4, 7.0u2, 7.5. If the Zerto version you’re using is 1 of the above versions, there is nothing needs to be done with Zerto before you upgrade the hosts. If the current Zerto version doesn’t support ESXi 6.5u3, please upgrade Zerto to the correct version first.
Please make sure the VRAs stay on the original host all the way as they cannot be v-motioned.
