We are migrating from Jira Cloud to Jira Datacenter.
While it was possible to keep the project key (here TPP) we failed to keep the issues Keys due to deleted issues in the source project key and integer assignment of issue keys on the target system.
Which results in TPP-912 is now TPP-546.
Is there any chance to assign individual issue keys when migrating issue from one instance to another?
Thank you in advance!
