We have done some migrations at the beginning of getting the Jira service management platform going but some data has been gathered on-prem since then and we would like to migrate the difference between what we had migrated earlier and what has been created since then. The question is, would the new data override the existing? We do not want to lose the configuration put into place and all the good stuff that we have done or does Jira intuitively does incremental capture since the last migration?
