Ensure that you are using Host Profiles version 6.0 or later. Host Profiles is a vCenter Server tool for designing and deploying ESX and ESXi hosts. See the VMware Product Interoperability Matrix at. vCenter Server 7.0 requires ESXi host version 6.5 or later. Verify that your ESX or ESXi host works with the vCenter Server version that you are upgrading to. Note: vCenter Server 7.0 uses PostgreSQL for the embedded database. Verify that your database is supported for the vCenter Server version that you are upgrading to.
Verify support for the upgrade path from your current version of vCenter Server to your planned upgrade version.
