I asked different versions for transfering our NPM witout interrupting the use. Unfortunately no one seems to work. Now I have a new Idea:
-I let the old NPM (8.x) running with the license
-I install the new version 10.x on different servers (NPM and Database) with a evaluation license
-I configure the new NPM within the evaluation time
-I transfer the license
Is that a way I can go?
