I previously installed Piwigo in a docker container using linuxserver/piwigo and linuxserver/mariadb with docker compose. Here link for reference: https://hub.docker.com/r/linuxserver/piwigo
With linuxserver/piwigo the piwigo config and images where in different volumes, now I can see that all is included in - ./piwigo-data/piwigo:/var/www/html/piwigo/
I'm wondering if it's possibile to migrate to your new official docker compose image, using my mariadb database container and upload image folder previously created by linuxserver/piwigo container.
Thank you
