For photos*, music, videos and other files (except apps), you may simply copy them to your PC then copy them to your new SD Card.
But for apps, this won't be possible. What I did for my L535 was to move all the apps to my phone (was fortunate that all my apps could be moved to my phone given that I didn't have a lot of apps), remove the SD Card, insert the new SD Card and then move the apps to the new SD Card. In case not apps can be moved in one batch, just move what you can in the first batch and then move the rest in a succeeding batch.
*- In my experience, once you've copied photos to a new SD Card, they will initially not be detected nor recognized by your phone. In fact, they would be classified under "Others" in Storage Sense. You need to use the
Files app, and just edit the name of each photo folder for them to appear in the Photo Hub. For example, if you've got a folder named "Vacation", rename it to something else (maybe "Vacationx") then rename it back to it's original name "Vacation". Once you open PhotoHub, you should see your photos there... or at least after your Photo Hub has updated its database if you've got a lot of photos.
