Without Plugins, how to copy Epics+Issues from ProjectA to ProjectB

[Darren]

Jira 7.8.2

Out-of-the-box - *no plugins possible*

I've created a templated Jira Project with Epics and Issues (and they're linked i.e. in the Scrum Board and Kanban Board's Backlog View the Epics Pane shows the links).

The ask:  to copy this structure into target Jira Projects preserving the Epic+Issue links.

CSV export and import is possible, however if this is the solution then I don't know how to preserve Epic+Issue links as rendered on Scrum/Kanban Boards' Backlog Views.

Without Apps, the closest you can get is to clone each issue in project A manually and then move the result to project B.

Thanks Nic,

It seems Bulk Clone isn't an option in a Bulk Operation (and elsewhere in this Atlassian Community it seems again a reference is made to Plugins).

Something else I tried:

CSV Export including Epic Link and Epic Name.

The problem with this is the Epic Link is the *source* Project's Epic, so that's doesn't work either.

Any further ideas from your good self, Nic?
