Hi,
A fresh install and content transfer is the only mode of updating at the moment (Coronium is technically always in beta). This will change shortly.
There is also a slight fragmentation issue between the plain Ubuntu installer and the AWS EC2 images which has created a versioning difference.
EC2: 1.93.1
Ubuntu: 1.93.5
The EC2 images will be updated to 1.93.5 shortly, as they require additional tweaks and propagation. Ubuntu installer is currently the most up to date version (as shown above).
We’re working to get this process smoother. I will write up a separate forum post with migration notes sometime today.
Also, Steve is correct, there is database seeding needed for an install.
Cheers.
