Hi! I made a bad move !

Hi, I made a bad move, to recover memory on my internal disk on my Mac mini, I only
 have 512 G, I transferred my Native plugins to an SSD disk, an Apple technician
 told me as stated that this was correct, after several listenings to tutorials 
on YouTube, I know why my plugins no longer work, there is a whole process to 
follow, I managed to transfer the vast majority, but there are 5 left that I am 
unable, and in my Logic Pro program, I do not have access to my plugins, what 
should I do to make everything work perfectly? While keeping my internal memory,
 and it works on my SSD?
And it's very hard to contact Native Instruments for a response
THANKS

Ron
