Snapshot appears to be stable (used TWSE to switch over). Confirming, then will perform migration overnight. Appears that the process will require about 15-20 minutes of downtime.

Snapshot complete.

Snapshot of server is being taken as of 8:20pm ET. Please do not make any changes to websites until complete. Snapshot will be used to transfer server to better hardware. 10-15 minutes downtime may occur.
