We have recently migrated OMS from Fedora Func to Saltstack and, unfortunately, extra work is required for migration.
To migrate to a new OMS/Saltstack system, the following steps are needed:
- Switch to OpenNode test repository by editing ‘/etc/yum.repos.d/opennode.repo’ and running ‘yum install opennode-tui’.
 - Resync and redeploy OMS VM.
 - Rerun OMS registration from HNs using the same process as before.
 
Thanks and sorry for the extra work.
