What are the formatting restrictions for a Project Key?

[Jeremy Lynde]

Can a Project Key have Slashes ( / or \ ) or Dashes ( - ) in it?

HI @Jeremy Lynde 

You can control the allowed format in the advanced config settings.

see https://confluence.atlassian.com/adminjiraserver/changing-the-project-key-format-938847081.html

You won't be able to change the basics i.e. must start with a letter, can only contain letters, numbers and underscore characters.

This is exactly the information I was looking for. Thanks.
