That's usually easiest...but if they are program installs and such that you don't want to have to resinstall, then it will be more work but you may be able to get around it. You will have to end up with 2 partitions on the larger SSD (SSD2) though.
Do you have an extra hard drive of any type where you can temporarily store backups? An external drive even? If so then something along these lines should work.
Create a backup of SSD2 to your extra hard drive.
Do a quick format of SSD2.
Create 2 partitions on SSD2. First one large enough for your OS. Second one the remaining space.
Clone SSD1 to partition 1 of SSD2.
Restore the backup of SSD2 to partition 2 of SSD2.
