3 ideas come to mind:
1. add a null and parent all the layers to the null (if the layers have parents, then just parent the parents of course). you can delete the null afterwards and your keyframes will modify to the new offset.
2. pre-compose all the layers and then move it as just one layer.
3. if it's 3D scene, then you can just move the camera since it controls all of the layers.
Null was the jam. Thank you!
Glad to help buddy. this workflow should have be written somewhere here: Adjust layer properties in After Effects under parent and layers, since it's a very important and useful implementation of parenting. even more that rigging a character in my opinion.
...and here's another way to do it, without using nulls:
- Reveal the position property on the layer to be tweaked
- Put the timeline cursor on one of those keyframes
- Highlight the position property on the far left; it highlights all the keyframes
- Using the Up-Down-Right-left cursor keys, tweak the position to suit
All the position keyframes are modified by the same amount. Very easy.

thank you Dave. this got me going back and forth for a second, but I double checked and Op wrote in the header: "Move all comp objects" so he probably means move many layers with animation keyframes together. if you want to move one layer at a time, one value at a time then the offsetting technique like Dave suggested makes sense.
for instance if you got this type of setup:
or even this:
then yes, you can offset the layer or layers as long as these conditions apply:
1. one layer - one keyframe is under your CTI, all keyframes are selected
2. many layers - all the keyframes are parallel under your CTI - i.e, at the exact frame in time, all keyframes are selected
(I wouldn't risk doing this technique with many layers though. only with one layer)
but if you have this setup - use a null
