If the OS is installed on the msata ssd, then you could just put the new ssd in and clone the main drive. After you migrate the data, remove the msata ssd and boot to the new drive.
Look up your laptop model number and find the manual that tells you where the screws and hard drive are.

keep in mind that DIY usually voids warranties
if you are replacing the hard drive, make sure you have a method to reinstall the operating system in case you mess up.
After you have your backup plan, find a "sata to USB" adapter or an external hard drive case to plug in the ssd while you load the OS.
After you've used the adapter to migrate the data to the ssd, you can swap the drives. You should be able to spot the hard drive as soon as you get the plastic bottom off.
Put it back together and turn it on. It should go straight to your regular login screen. If it has any problems, then do a clean install and copy your files afterwards.
