Trying to upgrade engine built from
commit:  dbc3d31110ce372a1fa7e06f64c4a5c64544c679

To latest engine built from latest master

running engine-upgrade results in:
 
***L:ERROR Internal Error: No Module named releasepreview

I know I must be missing something obvious?

The surrounding versions of otopi, host-deploy, etc do yum upgrade cleanly however.
