To upgrade or migrate the hosts in your vSphere environment, you must create host upgrade baselines.
Before you begin
Connect the vSphere Client to a vCenter Server system with which Update Manager is registered, and on the Home page, click Update Manager under Solutions and Applications. If your vCenter Server system is part of a connected group in vCenter Linked Mode, you must specify the Update Manager instance to use, by selecting the name of the corresponding vCenter Server system in the navigation bar.

- On the ESXi Image page, select a host upgrade image and click Next.
- Review the Ready to Complete page and click Finish.
