I have recently got an email stating me to migrate Fireflytools to Kubernetes cluster. By referring to the page https://wikitech.wikimedia.org/wiki/News/Toolforge_Trusty_deprecation, I started the migration. First I did the steps mentioned under the heading Move a grid engine webservice which I think has been successfully completed. Then I did the steps mentioned under Move a cron job after which I tried to do the steps mentioned under Rebuild virtualenv for python users. While doing those steps, the problem was that since there was no requirements.txt file, I was not able to upgrade to the latest version. Since the migration was only partially done, the tool is currently not working. I would like to know whether I can upgrade to latest version of Python without creating the requirements.txt file. The command qstat is also not working now.
