I completed all the steps satisfactorily, however, when I reached the step "Migrating the Base" executing the scritpt, I get the following error message:

[root@GILCSFOPPR01 tmp]# openproject run ./docker/mysql-to-postgres/bin/migrate-mysql-to-postgres
sh: /opt/openproject/docker/mysql-to-postgres/bin/migrate-mysql-to-postgres: No such file or directory

Thank you very much for your support.
