Converting local issue links to remote issue links

[bschmi]

Hi Community!

For several reasons I had to migrate main Jira project, let's say 'CENTRALPRJCT' from 'Jira A' to another Jira Server 'Jira B' (both on-prem) - worked ok.

On 'Jira A' the migrated project is untouched, up to now (but for obvious reasons it is read-only). Now several other projects on 'Jira A' are still linking (local issue links) to meanwhile orphaned 'CENTRALPRJCT' on 'Jira A'.

(?) Question: Is there any, programatically way, to "convert" all local issue links in several hundred projects on 'Jira A' to the same named project - meanwhile on 'Jira B'??
As this only affects the one moved project all other issue links must remain untouched.

Any hint or advise is appreciated.

BTW: I was able to fix the "Jira B"-side using: https://developer.atlassian.com/server/jira/platform/using-fields-in-remote-issue-links/

(!) Using this I was not able to create a reciprocal link though - and that's why I am asking here now on to if there is a chance to get the remaining projects on 'Jira A'-side fixed as well...

Thanks,
Birgit
