vSphere Embedded Linked Mode Upgrade from 6.7 U1b to 6.7 U2/ U3

[justinantony]

Hi Team,
Need a help to identify the order for the Vsphere Upgrade. I have gone through the vSphere upgrade guide which discuss about PSC-> VC and so on. However in 6.7 version onward we don't have external PSC as it got deprecated. Considering the existing Virtual center is 6.7U1b with embedded PSC and having linked mode what should be the order ?

1) Virtual Center (embedded PSC )  for Management
2) 4 ESXi Host

3) Virtual Center (embedded PSC )  for Workload

4) Remaining Workload Cluster/Cluster Nodes

As of now it is just mere an update for vSphere 6.7 hence Virtual center with different update works fine (I can see both infrastructure from both vc) however moving to a version change (For example 6.7 U3 to 7) how it would affect the environment ?

At present i don't have any replication or high availability for these virtual center however going forward does this impacts in similar situation ?

Top one is for Management and bottom virtual center is for workload.

Hi justinantony,

You need to look at the compatibility details between VC and ESX or remaining cluser nodes before upgrading.

Hi Bharat,

Yes i have gone through the compatibility matrix for the same however. At present my issue is with the Enhanced Linked Mode during upgrade scenario. If i upgrade one virtual center and 4 esxi host which is managed under the same virtual center and not upgrading the second virtual center which is linked with first virtual center then what happens during the major version change ?

1st situation

1VC Updated with - 6.7 U3

4 ESXi  Updated with - 6.7 U3 and i can retain 2VC with - 6.7U1.... (No issue currently as both versions are compatible each other)

2nd Situation
