Hi,

I have a precomp of 20 milliseconds, which I need to increase the duration to 20 seconds, however I need to move the keyframes proportionately with the composition duration.

Any advice?

You will have to do so manually..however, to move the keyframes proportionately you use the alt key technique to scale the keyframes  proportionately check the following video - https://www.youtube.com/watch?v=PFbFUvfMVgE

 

Or

 

You can use the plugin to automate the task i.e. Elastic-comp-changer -  https://aescripts.com/elastic-comp-changer/

If there is no video in the composition, the easiest thing to do would be to drop the shot composition into a longer composition, then apply Time Remapping and just extend the layer and move the last keyframe.

You might be able to get away with selecting the keyframes, right-clicking and selecting Rove Across Time.  This will refactor the inner keyframes to create a smooth curve, but it will also allow you to move the last keyframe and the others will stretch out accordingly.
