@girish Thank you so much!
This was the simple update method I needed to save a lot of headache. We'll need to edit some things to get ready for 8.1, but know it's as simple as editing a file and rebooting the app is such a relief.
@atrilahiji I know that Elasticsearch is stopped developing, from opensource into enterprise. And do we develop Elasticsearch from the latest opensource version?
@Nicolas One way to avoid this mistake is use getenv('CLOUDRON_MYSQL_USERNAME'), getenv('CLOUDRON_MYSQL_DATABASE') instead of the raw values. This way when you migrate next time, it will pick up the correct database connection values.
