I'm trying to upgrade a Synology DS218+ to DSM 7 and I have to uninstall MinimServer and java 7. When I try to downgrade a full license the page says it was successful, but when I try to uninstall MinimServer it fails due to the license is set to full. How do I fix my mess?
I am investigating this and I will reply when I have more information about what is happening.
From the license server logs, it seems you are deactivating the license from a Docker installation of MinimServer. You need to also deactivate the license from the native Synology DSM installation of MinimServer.
I fixed it by making sure all dockers were removed and then it was fairly easy. Thanks for putting up with me Simon.
