My company currently uses Jira service desk to support our customers who uses a software developed by another company. Both company uses Jira. Is there a way to integrate their Jira instance with ours so both sides will have access to one support desk? We want a more streamlined way to support out customers rather than out customers submitting a ticket from our Jira service desk then contacting the other company if additional support is needed. I rather want to have one instance where both companies can see when tickets come in as well as use a single library of workflows.
Update: Is there a way to integrate both our Jira instances to see each other's ticket ques and statuses if the above question does not have a less complicated solution?
