Hi All,
I would like to ask you for help which would be spare a lot of time for us.
Cover story:
we are migrating many Jira instances week by week to our master Jira. The problem is that all the projects in the most old Jira instances use more than 100 custom fields: and there a plenty of custom fields that are used by only 1 projects. This would be not so big problem but there are more than 70 global custom fields, about which we cannot tell that a particular project whether use the custom field or not.
Most of the time when we ask the users of a to be migrating projects that what are the custom fields they need in the new instance they tell e.g. 15 custom fields. But when it's migrating, we get the surprise that the project cannot be migrated because 22 custom fields do not exist in the new Jira.
The reverse is also used to happen: when we create a custom field for a migrated project but it was never used in the old Jira.
So we really need a tool or script which we could run and result the custom fields that have existing values in a particular project.
Thanks in advance!
