Hello,

The upgrade strategy in this case is as below:

  1. Backup Configuration
  2. Upgrade vCenter Server
  3. Upgrade ESXi one by one
  4. Upgrade virtual machines and virtual appliances

Before to start the upgrade process, it is recommended to check your host compatibility with the target version through the VMware Compatibility Guide: VMware Compatibility Guide - System Search

And regarding the vCenter upgrade also be careful if you have an external configuration. (external PSC and vCenter).

For more information check the following: https://docs.vmware.com/en/VMware-vSphere/5.5/vsphere-esxi-vcenter-server-552-upgrade-guide.pdf

Please consider marking this answer "CORRECT" or "Helpful" if you think your question have been answered correctly.
