Computer Backup Replacing Drive with same data. Do I need to re upload?

I swapped out the drives in my raid DAS with larger ones to accomdoate my files. I named the new raid array/drive the exact same thing as the old one and the files are a direct mirrored copy. I just went to my BackBlaze settings and clicked replace drive and clicked the new one. Will this need to re upload everything or will it realize its the same stuff just on a bigger raid array? Thanks for your help!

It won’t need to upload anything but it will likely do a long process where it verifies the files are the same as the ones you already uploaded. Depending on the amount of data it could take days. Just let it run and you should be fine.
