Desable issue link between two projects

[Guillaume Chaperon]

Hi, we've been using a project for an older version of our software in Jira, and we've created a new one today. When I try to link two issue, issues from the older project are shown in the list of linkable issue. What can I do to not shown issue from an other project when i'm trying to link two issues ?

In fact, I don't want any interaction between these two projects.

Kind Regards,

Guillaume

Guillaume,

You can setup the old project so it is unable to link to any other projects or tasks within that project by changing the permission scheme.  Update the permission scheme so the link issues does not have any permissions to do so.  You will want to make sure that this project is the only one with that permission scheme or you will remove that permission from other projects as well.

I've try to change the permission scheme but nothings seem to have changed. 

I'm wondering if this is about the new generation of project, there is so few customisable options for new agile projects in jira cloud..
