+1 for code-first migrations. It's a bit of a learning curve, but the effort is worth it imo.
Create an SQL project that defines the schema. It automatically compares the schema with your current dB schema and auto generates a migration script for you.
Then update entities from the dB.
Few steps involved but avoids writing and maintaing migrations yourself.
I don't want to go back to any sort of migrations outside of this.
