- create command should be run with --date-format to be more human
readable, and --template-file to use our template instead of migrate's
default
- rename migrations
- rename createdAt to migratedAt to remove ambiguity
- do not merge relationships for Location nodes as we don't want to
create duplicate relationships
- use singular locationId as it's iterating one at a time
- having duplicate Location nodes in the production database blocks us
from adding a unique constraint, so that Locations are not created
which have the same id.
