“FlywayException: Detected failed migration to version 1.0”
it means that you ran migrate before and it failed at 1.0 for some reason. You need to identify why the previous migration failed at 1.0 and solve it if you have already not done so.
Once solved you need to run flyway repair to tell flyway that whatever failed is now out of the way.
Then run flyway migrate again. If it fails again, you are back on step 1.
Good luck with the migration.
