downloaded and copied over the pre-built hydra binaries (while node is running - this works fine since it doesn’t affect what’s in memory; just don’t restart anything yet)
downloaded the db from csnapshots
stopped the node
deleted the old db folder, unarchived the csnapshots in the proper db location
rebooted
Once rebooted, the node finished syncing the remaining blocks in under 10 mins. It was at 99% in 4 mins. I’m very happy with this flow and will use it next on our bp.
