Steps to patch a Windows Based VMware vCenter Server 6.X
-----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------
- Please take a non-memory, non-quiesced snapshot of the vCenter VM (if standalone), before implementing any change.
- In case there are multiple vCenter servers linked, do take powered down snapshots of all nodes before proceeding with vCenter update.
- If PSC is external do take powered down snapshot/s of all PSC's as well.
- If there are multiple vCenter's linked with external PSC we need to update all PSC nodes first and then proceed with vCenter nodes.
- If DRS is set to Fully Automated, please change it to Manual while updating.
- Make note of the host IP/FQDN where vCenter/PSC VM is deployed.
- Ensure that you have the login credential for the ESXi host which has the vCenter VM.
