The new wall shiplap joint in place

This picture shows the wall with the old without frame mirror removed. The old retaining clip holes will be filled with gyprock compound, sanded and painted.
The new framed mirror has a fifty degree angled frame, which gives the back of the mirror a one and a quarter inch deep recess. The person in the store who sold the mirror recommended placing eyelets on the frame, and to use a wire and hooks to hang the mirror. The wire and hook method of hanging a mirror, causes a mirror to tip forward at the top and be very unstable on the wall, especially a heavy mirror.
The solution offered here is a wooden shiplap joint hanger, to secure the mirror to the wall. This hanging arrangement causes the mirror to be stable, level and snug to the wall.
Remove the mirror anytime, by simple lifting upward one inch, and pulling the mirror towards you. The wall hanger shiplap is shown in place.
shiplap joint in place on the mirror

This picture shows the shiplap strip in the back of the mirror frame.
To, make the hanger strips, take a two by four, and cut it in length, to the width of the frame. Cut the 2x4 down the middle length wise, to make two 2x2s. Use the 2x2s to make the shiplap joint. Cut a 3/4 by 3/4 inch notch the full length of the 2x2s. Cut the combined 2x2s shiplap joints too thickness, so the joint will fit level, in behind the mirror, with just a little play. Plane the edges of the shiplap joint, and lightly sand all the pieces. Place one half shiplap joint onto the wall, and the other half on the backside of the mirror.
Cut the behind the frame shiplap joint ends at fifty-degree angle, or to whatever the frame requires. Apply glue to the end of the joint, place the hanger one third of the way from the top of the frame, install to the frame with two five eights inch screws.
To attach the wall hanger to the wall, find at least one stud to secure too. Countersink the screw holes, so the screws are below the surface of the wood. If there is no stud to secure the other screw to, place a gyprock screw type fastener into the gyprock. Level the hanger, and screw down the shiplap hanger.
Place the mirror to the wall and lower onto the shiplap joint.
Tip
To adjust the mirror to the wall, shim behind the wall shiplap for required play.
