Hi
You will find your bookmarks and login data as shown in image (W11 64bit), in old ssd.
bookmarks is for favorites: you need to convert it to htlm @ https://rongjiecomputer.github.io/chrome/bookmark-recovery/#windows
then import the converted file from Brave.
login data is for login to sites: You can use chromepass app from Nirsoft to get your old passwords. This post may help in recovering your passwords.
NOTE: Before copying anything from old ssd to new ssd, make a backup of your bookmarks and passwords!
