Dear community, is there a “direct” upgrade way from CE versions: **5.12 to 6.2**? or do i need to do the upgrade from **5.12 to 6.2** in two steps: - opennebula upgrade from 5.12 to 6.0 (onedb upgrade from 5.12 to 6.0) - opennebula upgrade from 6.0 to 6.2 (onedb upgrade from 6.0 to 6.2) ---

You don’t need to, please check the [upgrade guide](https://docs.opennebula.io/6.2/intro_release_notes/upgrades/upgrading_single.html#upgrade-single). There are multiple sections according to the version you are upgrading from. ---

btw - when i would rename the migrator: **6.0.0\_to\_6.2.0.rbm** to **5.12.0\_to\_6.2.0.rbm** the onedb upgrade -v would run in one touch (so it should be) …but i’m not sure if this right approach. ---
