Hi,
Struggling to find sequence of steps to upgrade vCenter 5.5.0-3252642 version to 6.5.
what are the pre checks and outcome will be ?
Also, after upgrade to 6.5, can I able to manage ESXi hosts of 5.5 and 5.0 versions.
Need your insights,
thanks
This is pretty straight forward if you have small infra with vsphere 5.5, like you have all vCenter components on single machine. It also depends how you want to distribute your 6.5 architecture as 6.x version has PSC controller which isn't there in 5.x. I am sure you are aware of it. The steps would be :
1. Check prerequisites and requirements : https://docs.vmware.com/en/VMware-vSphere/6.5/vsphere-esxi-vcenter-server-65-installation-setup-guid...
2. Backup current configuration.
3. Upgrade vCenter (if you have SSO separetly then upgrade it first to PSC, then upgrade vSphere web client if it is installed separetly)
4. Upgrade Vsphere Update Manager.
5. Upgrade ESXI hosts.
6. Upgrade virtual machine's tools and hardware.
In step 3, if your existing vCenter has all roles on single machine then upgrade path is straight forward. If not then upgrade :
1. single sign on.
2. vCenter
3. vSphere webclient (if installed separately)

Hope this will be helpful.
