Moving module location
You can do this without uninstalling, but it takes some fiddling:


Move the module in filesystem
invoke drush ev "drupal_flush_all_caches();"
invoke drush cr


The crucial setting is the entry system.module.files in key_value database table. If you move the module(s), the try to run drush cr directly, it may fail because drush tries a full bootstrap and fails to locate the required files.

drush ev does an error-free bootstrap using drush_bootstrap_max(), and drupal_flush_all_caches rebuilds system.module.files config without trying (and failing) to load the moved files. Whereas drush cr does a full-site bootstrap, which causes drush to halt on any errors.
