The official documentation, “Migrating data from MongoDB 3 to 5”, wants to dump the MongoDB databases in 3.6 and then restore this data into the newly deployed MongoDB 5.
One issue with this process is that we can’t run the two MongoDB versions in parallel on Kubernetes because the provided helm charts and container for MongoDB 3.6 stop running after Kubernetes 1.21. On the other side, the helm chart providing MongoDB 5 can’t be installed on those old Kubernetes versions. So the process to update is:
- Dump databases in MongoDB 3.6 (version delivered with Connections 7)
- Update Kubernetes to 1.25 or 1.27
- Restore MongoDB databases to version 5.0

After updating HCL Connections to 8CR3 and Tiny Editors to 184.108.40.206 the lines of tables are no longer visible during editing.
Here is the edit form with Tiny Editors 220.127.116.11:
During a troubleshooting session in Component Pack, I checked the Kubernetes events.
Elasticsearch in HCL Connections Componentpack is secured with Searchguard and needs certificates to work properly. These certificates are generated by bootstrap during the initial container deployment with
These certificates are valid for 10 years (
chain_ca.pem) or 2 years (
elasticsearch*.pem) and stored in the Kubernetes secrets
elasticsearch-7-secret. So when your HCL Connections deployment is running for 2 years, the certficates stop working.
