Local install EN user here. I first quit EN and restarted the MBP. Moved my "accounts" folder (~34 GByte) to an external drive. Went in Terminal to the Library folder where accounts resided and entered ln -s <path to the moved accounts folder, e.g. /Volumes/SSD07/EN/accounts/> accounts which creates the symlink. Started EN, there was a dialogue window showing up very shortly telling that some user data gets migrated (?). EN is fully functional and I saved some 30+ GByte on the local drive
Thanks pherman, works for me, too!
