I went ahead and started the upgrade of the backup drive on the server. Due to the size of the site it is going to take about 8 hours or so to perform the migration and get things back up and running.
I have scheduled this for 8pm EDT on Sunday May 11th.
The site will be completely down for that time while the new drive is installed and everything is set up correctly.
Feel free to follow our social media pages and I will keep you informed on developments via those.
