How do i Migrate windows partition from large HDD to SMALL SSD?

I have just got a 120gb SSD and i put it in my laptop along with my 1tb SSHD and my 32gb Mssd.
now i would like to have this as my final output


120gb SSD holding ONLY windows files/installation and possible some small apps (bootable)

and my large 1TB for everything else (non bootable) used for raw storage, Games, data, apps/programs

i keep reading things on google that people can do this but whenever i try even with the same software i get things like "the destination drive is smaller then the source drive")

can i achieve this?

Now, though, if the original source partition has more space used on it than the target SSD will hold, you will need to move some stuff off the source partition to get the used space down to less than the capacity you have left on the SSD after you copy over the system and recovery partitions (copying over the recovery partition is optional).

I have about 857gb used out if my 1tb

and as i said ALL apps just says the destination drive is smaller then the source drive

How do you propose to fit 857GB of data from the 1TB HDD to a 120GB SSD? Is the 857GB all in one partition?

I was maybe expecting to selectively move just the windows critical files.
My Windows is setup in a complicated way with a series of systemlinks.

Again, it all depends on what is in which partitions. You can only clone a partition with less than about 90 GB used space to a 120 GB SSD and still have room for a system partition and recovery partition.

My data And system partition seems to be together

Probably your best bet, then, is going to be a clean install of Windows to the new SSD.

Well I have used systemlinks to fix a lot of issues in Windows before so perhaps going full systemlinks and redirecting paths on a dirty install on the SSD may work?
