JIRA delta data export and import

[Amit Anand]

I have exported full dump of jira instance A and imported in another jira instance B now after few days development are still going in jira instance A so now we need to import delta data to jira instance B 

I am looking a way to export and import delta data of jira from instance A to B.

first things first - shutdown access to Instance A. 

It can get messy depending on what changed. I am assuming you are going to use CSV import here. 

First the easy part. You will want to run a query to find all issues in instance A that were created after your import to instance B. So you need to know exactly when you did the last export then use that date and time to run your query. Once you have that result you can actually use it to import just as you did before in the instance B. 

Now, for the stuff that changed post import. You will use the same date time and create a query that leverages updateddate JQL function. Get the results into excel. Now you will then need to add a column that has the issuekey from your instance B for each row before you import. By including the issuekey the import function will update the current issues. Of course if the list is small just manually update.
