mySQL Database Migration fails due to "null" character in Bitbucket Server table
症状
The following appears in Bitbucket Server 2.7.1 Migration Setup UI:
Bitbucket Server could not be migrated to the new database. Some data may have already been written to the new database leaving it in an inconsistent state. You will need to empty or recreate the new database before trying again.

診断
Migrating to a clean mySQL database on Bitbucket Server 2.7.1 with the presence of the character "null" in sta_pull_request table will result in a failure of the migration that will return the error on the screenshot above.
This only have been tested on Bitbucket Server 2.7.1
Direct update to the database may cause database corruption
ソリューション
Update to at least Bitbucket Server 2.7.6, then only perform the migration.
