Are we able to have more than one sprint active at a time on a board?

[Phearom Sin]

What about on a project? We ask because we are trying to decide if a client that has multiple “lines of work” associated to it should be broken out into different projects and/or boards.

[Jobin Kuruvilla [Adaptavist]]

You can have.parallel sprints enabled on the board. Depending on the version of your JIRA, this might be a labs feature (Server) or part of default functionality (Cloud).
