My go to migrator is fluent migrator (https://github.com/schambers/fluentmigrator) or flywaydb if anyone objects to the c# (https://flywaydb.org/).

Each migration gets a number, typically time encoded. If I was to write one now it would have the attribute [Migration(201608251157)]. With the new literals this will become [Migration(20160825_1157)], amazing how much readability a single underscore can make.
