Is replacing the stock SD card as easy as it seems?

[Ryum]

I have a 32 gig sd card I have from a previous phone. I want to put it into my new EVO, and I don't want to lose what info is currently on the stock SD card. Do you just simply plug the phone to the PC via usb cord and pull all the folders and ect off of it and put it onto the PC then take out the battery and put it back onto this new card?

It seems like an easy process which is why I ask if this is how it should be done. It seems like Everything I have done with SD cards lately, what seems like the easy direct way doesn't usually work.

I called sprint about this and 3 tech support people in a row so far and 2 didn't even know the EVO came with an SD card and the third said the SD card can't be taken out... which is dumb.
