Greyhole UI App Transition Guide
From Amahi Wiki
The automated option is designed for new Amahi 7 installations and the preferred method of install. It does not support previous manual Greyhole installations, meaning all your current Greyhole settings will be overwritten. Recommend you back up or note your settings from /etc/greyhole.conf, shares that are Greyhole enabled, and the number of copies for each prior to installing the plugin.
You can then follow guidance in Greyhole Advanced Options to add any settings not included in the automated configuration.
