Help Changing SD's 32G to 64G

The 32G SD in my MAXX is slowly running out of space (photos, MP3's & 4's). I decided to try a 64G SD. I copied what I thought was everything on the 32G to 64G SD and plugged that into the MAXX. The SD works, and there's a lot of data on it, but not everything. For example, PlayerPro is missing 2/3 of the MP3's it should know about. Using FX, I figured out that sdcard-ext's contents have all of the missing files. Right now I'm copying all of that to the SD but I have a feeling I'm wasting my time, because I probably don't have the file structure right.

Question: what is the best way to migrate the contents of an SD from one SD to another? Helium? Simple copy, or...?
 
Well, that's what I thought would work, too. The problem is it only partly works.

When I put the 32G SD in my laptop, I get two devices (well, ignoring the Moto-whatever partition). One corresponds to sdcard-ext and the other is sdcard. The challenge is to correctly partition the 64G SD the way the 32G SD is partitioned. Once I have that right, drag&copy should work. But maybe a backup app is a better choice?
 
It's clear I don't understand something about the MAXX's file structure.

Specifically, /storage/sdcard0 seems to be a link to /sdcard and /storage/sdcard1 seems to be a link to /sdcard-ext.

If I create an image of sdcard-ext (or /source/sdcard1) and put that image on the 64G SD and plug it in, I should see the same files in sdcard and sdcard-ext. That doesn't seem to be happening.

I looked at apps like helium and all they seem to want to do is backup apps, not wholesale file backup.

Again, the object of this rain dance is to move all of a 32G SD to a 64G SD and see everything as it was, only with a lot more free space. So far, that's not happening. What am I missing?
 
Drag and drop finally worked. I copied /storage/sdcard1 to my laptop, and from there to the MAXX.

There were intermediate steps though. My laptop, even with a USB card reader, refused to read the card. (Oddly, it did read it at one point and then stopped doing it) I put it into the MAXX, scrolled down the SD card area of the Storage option in Settings, and formatted the SD card. After that, I used a USB cable and copied the contents of the 32G card onto K: (sdcard1). All better.

ADDED: BTW all of the above shows a MAXX will accept a 64G microSD. Using Clean Master, it confirms I have 64G available on sdcard1.
 
did you format the new sd 64gb card in the pc or in the phone? what format did you use? NTFS?
so you copied the folder over to the new sd and it worked or copied the folder contents. can you be more specific ? im about to wipe my phone because it keeps crashing and i bought a new 32gb microsd because the partitions on my phone are all jacked up and small
 
I can't remember diddly about how I got the 64G microSD going. OTOH, that means whatever was needed was mindlessly simple to do. 32G microSD's should be equally easy - again, I don't remember how I got the 32G chip going, either. So I assume it's all easy-peasy.

I checked the file system on the 64G chip: FAT32. BTW, I came up with 58G usable. I'm not sure what's up with that, but that's bigger than 32G -WIN!

My guess is the phone doesn't understand NTFS. But, hey, you can try it.
