I've tried different approaches and none of them were simple and elegant enough to make the cut.
I've created a board using a filter involving all of our company's project so yes, you can track them but when it comes to creating one from this "Support" project, there's no way to move them to another project's backlog. One way was to create an additional Sprint in every other projects and naming them "X Team Support Backlog" so it could be placed in a separate "backlog" to be groomed accordingly but this is just messy and overkill to me.
Other than that would be to actually Move the ticket in the setting to convert them to the chosen other project but then it changes the key and you lose the track from the "Support" stand point.
There has to be a simpler option that Jira offers to handle those cases and I can't seem to come up with one so far nor to find an answer to my situation when searching online.
Anyone of you had this kind of issue and what ways did you use to handle this?
Thank you in advance!
(This is actually my first question here so be gentle if I somehow did something wrong hehe)
