Moving applications to different drive on Mac

[barbaraa6698934]

I installed a larger SSD on a 2017 iMac (which had a built-in SSD previously).  So the new external drive is larger, but not quite as fast as the old internal one, and the CC applications are slower than before.  I see the option to change the default install location in CC, but changing that doesn't MOVE my existing apps to the internal drive.  My worry is that what I have to do is uninstall and reinstall the apps to get them to the new location, and I worry that if I did that, it would reset all my customizations etc.  Any advice on what to do?  Can I simply drag the app out of the external drive's applications folder into the internal drive and go from there?  Or is this more complicated than that?  Thanks!

Barbara, what process did you use for the apps to be moved off the internal SSD?  Was a copy of the internal drive made to the external drive?  Which drive currently contains the host operating system the is running the iMac?
