Migration from "old" to "new" Microsoft Windows (10 to 11)

if I have to reinstall everything from scratch, can I

a) at least spare the tedious DAYS it takes to download humpty gb of NI_libraries (and Soniccouture and and and and)?

Reinstalling a Komplete Bundle Without Re-Downloading Kontakt Libraries

Moving a Native Instruments Product to Another Location on Your Computer

Using the Repair / Relocate All Function in Native Access

b) will I get an extra licence for this purpouse (like I do for Steinberg's Dorico and WaveLab)?

No , but from what other people says then N.I. do not appear to be very hung up on installation as long as you do not abuse your license , however you still have to run it by support if you want any official statement.

Ref. : Quote : END USER LICENSE AGREEMENT , section : 3.3

Licensee may install and personally use the licensed software on three devices (e.g. one computer, one laptop, one workstation), provided that the said software is used only on one device regularly. Simultaneous use on more than one hardware device is not permitted. The Products may not be used on a network by multiple users, unless each user possesses a license. In case Licensee changes the hardware, all software on the hardware used must be deleted.
