Hi.
I want to install Mayan EDMS, but their docker-compose.yml is version 3.7.
I am afraid that if I upgrade docker-compose (I don't know how :-)), I'll lost my docker nextcloud/letsencrypt configuration, which is version 2.
The question is: is it possible to upgrade docker-compose to read ver. 3 yml files AND to upgrade my old yml files from 2 to 3?
Any help is appreciated. Thank you.
