2] Install latest Trilio release
Please follow this documentation to install the latest Trilio release.
3] Enable mount-bind for NFS
This step would be needed only when your backup target is NFS and if you are upgrading from T4O 4.1 or older releases.
T4O has changed the calculation of the mount point from 4.2 release onwards.
It is necessary to set up the mount-bind to make T4O 4.1 or older backups available for T4O 4.2
Please follow this documentation to set up the mount bind for RHOSP.
4] Enable Global Job Scheduler
After the upgrade, global job scheduler would be disabled. You can enable that either through UI or CLI.
4.1] Through UI
Login to the Dashboard and go to Admin -> Backups-Admin -> Settings tab and check the 'Job Scheduler Enabled' checkbox. By clicking the 'Change' button you can enable the Global Job Scheduler.
4.2] Through CLI
Login to the any WLM container, create and source the admin rc file.
Execute the enable the global job scheduler cli.
$ podman exec -itu root triliovault_wlm_api /bin/bash
$ source admin.rc
$ workloadmgr enable-global-job-scheduler
Global job scheduler is successfully enabled
5] Import old workloads existing on the Backup Target
Workload import allows importing Workloads existing on the Backup Target into the Trilio database.
Please follow this documentation to import the Workloads.
