[aur-general] Transition users from package x to package y (package x deprecated)

[Michael Kogan via aur-general]

Hi guys,

I maintain the multiload-ng AUR packages, in particular
xfce4-plugin-multiload-ng-gtk2 and xfce4-plugin-multiload-ng-gtk3. After
the recent Xfce 4.16 update the gtk2 version stopped building, so I would
like to delete xfce4-plugin-multiload-ng-gtk2 and somehow migrate the users
to xfce4-plugin-multiload-ng-gtk3 (which should be renamed to just
xfce4-plugin-multiload-ng if possible). What are my options making the
transition as smooth as possible?

Thanks for any input and merry Christmas!
Michael
