Upgrading disks

I currently have a single 1-TB drive in my EX2 and want to upgrade it to the 2 new 3-TB WD Red drives that I just purchased. What would be the best way to do so without losing the current configuration that has Wordpress installed. I also have a bunch of eBooks and iTunes music on it but I’m not worried about backing up that as I can just copy those files over to my Synology NAS. Just not sure how to save the Wordpress configuration - e.g. are there hidden system files that would not get copied if I just tried to copy all the files on the EX2 over to the Synology NAS, then copy them back after installing the 2 new 3-TB drives in the EX2?

Hello there,

I have not tried this, the only thing in my opinion that can change is if the app is related to a specific share. Lets see if another user can share some information or tips on this matter.
