Thanks for the feedback Ben!
I will need to search how to deal with this considering that are a lot of modules do not support version 7 yet (at least from a documentation perspective).
But to be honest I was expecting a minimal way to use the 6.x version. Would be an alternative building at the latest every X months? This way at least we would have an option to update every X (3 months for example) until the EOL of Dec 2022.
Thanks for the help and info!
