Migrating BitBucket and Circle CI to different team

Prabu.Murugan

We recently got an requirement to takeover a set of repositories from different team and we are in the process of migration. 

We followed the approach provided at https://bitbucket.org/blog/transfer-repositories

But the issues that we use currently are - 

1. There were CircleCI builds that were configured for the repositories and they get migrated. But, we see that context variables/environment variables weren't moved across. Is there a way we can migrate these variables during this migration process? 
2. This is manual process, since there are 100+ repositories, is there a way we can move all under particular team to our team?
