Within the instances I manage there are several projects that have issues dating back for years. The projects themselves can't be archived but I'd like to provide guidance to the project admins to consider archiving some of their issues per Archiving an issue
These older projects also have some niche fields and issues types which we would like to plan to remove or add to our deprecate list.
If I'm searching for field or issue type used in the live/cached instance I could be lead to believe a field is low or not used and decide to remove it (reassigning issues to a new field or issue type during the process). What happens to the archived issues that may be using the field or issue type? If some decided to un-archive the issue I can predict there will be errors. But, maybe Atlassian was proactive and has built in a migration process to the un-archive. If anyone has tested this or has any input I'd love to hear from you.
