This is what I used to have composer 1 & 2 both in the same machine. I am hoping this will helpful for someone, who want to use composer 1 & 2 both as separate command

Keep Composer 1 & 2 as separate command

Setup Composer 1:

  1. Copy the current composer directory to new

    cp `which composer` /usr/local/bin/composer1

  2. Update it to version 1:

    composer1 self-update --1

Upgrade to Composer 2 & create alias:

  1. Update composer to version 2

    composer self-update --2

  2. Create symlink for composer2 (optional)

    ln -s `which composer` /usr/local/bin/composer2

Now you can use composer or composer2 command for the project dependent on composer 2 and composer1 command for the project have dependency on composer 1.

Note: you might required to use sudo before the command
