+Depending on the storage medium, this may take even longer.

+WARNING: This migration process cannot be interrupted. If it is, the chainstate
+will be **irrecovarably corrupted and require a sync from genesis.**

+WARNING: You will need **at least 2x the disk space** for the migration to work.
+This is because a copy of the chainstate will be made in the same directory in
+order to apply the new schema.
+
+It is highly recommended that you **back up your chainstate** before running
