Questions first:
1. What size is the new SSD?
2. How much data, total, is on the current HDD?
3. How old is the current install? Does everything work to your satisfaction?
There are two options: Migration from old drive to new, or a clean install on the new SSD.
1. The new ssd is 60GB
2. Currenly i have 148GB but it has bunch of random files from many installations
3. The current Windows 8.1 Pro install is like 2 days old
1. 60GB is right at the edge of 'too small'. Yes, it will work, mostly. But you'll really be chasing free space on that drive. For an SSD, you need to keep 10-15% free, so that reduces your actual usable space to around 50GB.
A current Win 8.1 install weighs in at around 30-35GB once all the updates are done. Win 7 around 40-45GB.
So with nothing else installed, you're already bumping up against that size limit.
Since it is only 2 days old, I'd just start over.
Remove all drives except the new SSD, and reinstall the OS.
If you wanted to migrate, you'd have to pare down that current install to 50GB or smaller. Much easier/faster to just start over.
