Jira Automation - if ticket updated, also update linked issue

[David Washburn]

Hi, we are trying to create an automation rule that allows us to keep two issues exactly in sync. When a field is updated on one issue, the linked issue will also have that same update. Is there an easy way to do this with automation?

The only way I can think of is creating a rule for each possible field that could be updated, but that sounds insane. Is there a way to handle all of those possible "if" within one rule? I guess it could be a huge If/Else?
