Hi @kingsly kwalar . Do you mean that you moved from one server to another and you want to check when this was done?
If this is the case, Jira does not record migration history. It does record upgrade history.
If you have migrated for example from a Linux server to windows you may be able to track this by checking the startup logs when this was changed. As it on 29th the OS on startup was Linux, and on the 30th the OS is Windows.
Is there a reason why you would want to get such information about the instance?
