Migration from 0.8 to 1.x

Hi,

Have some questions before trying to migrate drone server from 1.0.0-rc.5 into 1.10.1

  1. Is this tool [1] still works for our migration usecase?
  2. We are using the external database backend(mysql) [2] and wondering
    is it possible to keep and transfer the original repo build job logs into the new drone server?
    The db schema between these two different versions will be the same?
  3. So is the following steps suggested for migration?
    1: prepare another new env
    2: testing pipelines on it
    3: and finally switch to this new env

Thanks
