This may be fairly simple we are migrating from Jira 1 to Jira 3 I need to migrate a dashboard that will be similar to Jira 1 moving into Jira 3.
Welcome to the Atlassian Community!
Jira 1? Wow, that's very very old. I've been an Atlassian admin since <mumble date that screams that I'm old> and I started with a Atlassian between Jira 2 and Confluence 1.
But, Jira 1 to Jira 3 is not difficult, as long as you go through Jira 2.
I have a feeling that your numbers are local to your systems, not actually Jira 1 and 3. Coould you tell us a bit more?
