How can I export information that I have in an Jira instance server?

[Sofia Grunspan]

I have an instance (Jira Software) which issues has a lot of information in attachments, links, and others. this Jira instance/site is going to be depprecated and I want to take out all the information that is there. All the projects, issues, attachements.

There is a way I can do that? There is an add on maybe that will help me to export all?

Remember this is server.

Thanks!

The only useful way to do this is to take a full backup of the system, in a format in which you can restore it to another (temporary or development) Jira system.

Or, you will need to write something to scrape and export every issue into a format you want to keep.

I'm not aware of any apps that can do the latter.
