Nodes not updating last check in time

We are in the process from updating from Chef Server 12.5.1 to Chef Infra Server 14.5.29-1. I have migrated our data from Chef Server 12.5.1 to the new Chef Server using knife-ec-backup/knife-ec-restore.

I can connect our clients to the new Chef Server. However, for some reason, when I search for the connected clients in Chef Automate, it seems like the Last Check-In time is not updating. The clients are running Chef Client 12.13.37-1.

Is there something else I need to add, in order for the clients to show that they have Checked In, in Chef Automate?

Any help would be appreciated. Thank you.

To Reproduce
1/ Navigate to Automate UI > Infrastructure > Client Runs -- See the check-in time of the node.
2/ Navigate to Automate UI > Infrastructure > Chef Infra Server > Nodes -- See the Last check-in time of the node. Last Check-in time is empty for all the nodes.
PFA the screen shots.

Expected behavior
Last Check-in time should be updated on the nodes section in Automate UI.

Start by reproducing the issue in the Automate UI under Infrastructure > Client Runs and Infrastructure > Chef Infra Server > Nodes, using the stated Chef Infra Server and Chef Client versions. Compare the client-run check-in data with the empty node Last Check-in field; done means connected nodes display an updated Last Check-in time.
