Follow this vSphere upgrade order, otherwise you can lose the connection between an ESXi host and vCenter. If you need to update ESXi to ESXi 7.0 Update 2 in vCenter, you need to update vCenter or deploy vCenter 7.0 Update 2 first. Thus, you have to upgrade vCenter first and only then proceed to the ESXi upgrade if you want to upgrade vSphere 6.7 to 7.0. VMware vCenter 7.0 can manage ESXi 7.0, ESXi 6.7 and ESXi 6.5, but vCenter 6.7 cannot manage ESXi 7.0 hosts. If an ESXi host is managed by vCenter Server, the vCenter version must be the same as the target version of ESXi after the upgrade or higher.
