keypoints about how to add flyway migration in spring boot

1- add dependency:

<dependency>
            <groupId>org.flywaydb</groupId>
            <artifactId>flyway-core</artifactId>
        </dependency>
<!-- https://mvnrepository.com/artifact/org.flywaydb/flyway-database-postgresql -->
<dependency>
    <groupId>org.flywaydb</groupId>
    <artifactId>flyway-database-postgresql</artifactId>
    <version>11.3.3</version>
    <scope>runtime</scope>
</dependency>

note that here we are using postgres that's why we used it. you need to add database dependency of which you are using.

2- set up properties

spring.flyway.enabled=false
spring.flyway.locations=classpath:db/migration
spring.flyway.baseline-on-migrate=true
spring.flyway.baseline-version=0

3- add following configuration in java code:

@Autowired
    public void FlywayConfiguration(DataSource dataSource) {
        Flyway.configure().baselineOnMigrate(true).dataSource(dataSource).load().migrate();
    }

4- as configured in properties file, add migration sql script in db/migration directory with file name of this format "Vx__file_name.sql'' where x is number of migration like 1,2,3 etc
