In VMware NSX, Pre-check shouldn't be initiated until the Upgrade Coordinator is upgraded.
Workaround:
Due to incorrect procedure, pre checks triggered before UC is upgraded, a file is created in this location:
/image/upgrade-coordinator/migration-progress.jsonTo workaround this issue, please proceed with the below steps on the orchestrator NSX Manager node:
- Delete the file that was created due to the pre-check being run after the MUB file was upload:
rm /image/upgrade-coordinator/migration-progress.json
- Restart the upgrade coordinator to clean up stale mub-upload-in-progress flag file:
service upgrade-coordinator restart
- Then retry UC upgrade by clicking on "Begin Upgrade" button on Upgrade UI, and proceed with upgrade.
