- Operations Manager (Ops Manager) 1.x and 2.x
In some cases, you may want to revert to a previous version of a stemcell. Perhaps you accidentally uploaded a newer version or you are having a problem with the newer version.
Ops Manager always uses the latest stemcell uploaded. If you accidentally upload a stemcell that is newer than the one you intend to use, you cannot roll back through the Ops Manager UI.
Ops Manager stores uploaded stemcells under `/var/tempest/stemcells`.
To resolve this issue, you need to SSH to the Ops Manager VM and manually delete the stemcell.
You will then be able to upload a new and valid stemcell and the Ops Manager will use that file instead.
