I'm working through a trial migration of Jira Server (8.6.0) to Jira Cloud, and the documentation ( https://confluence.atlassian.com/cloud/what-gets-migrated-with-the-jira-cloud-migration-assistant-993925216.html under "Adding Additional Entities with CSV" ) says to export issues to CSV in order to import the custom fields into Jira Cloud.
Almost all issues we have are going to have custom fields, so my empty search returns all 22,000 issues we have. However, Jira only allows 1000 issues to be exported at a time. I suppose that's fine, I can concatenate 22 CSVs, I just don't know how to export them in 1000 issue segments. Is this possible, or is there some other way I should be handling it?
Sorry, I should've mentioned I'm using the migration assistant. And some custom fields aren't supported in migration https://confluence.atlassian.com/cloud/what-gets-migrated-with-the-jira-cloud-migration-assistant-993925216.html
There is a workaround. Kindly have a look at this page
it's the same idea.
Or you can use the rest api to fetch data and generate own csv.
Or review xml and generate csv data
Or sql queries to get the exact fields data (many joins :) ).
Or Extend limits for search and export https://confluence.atlassian.com/jirakb/how-to-increase-the-jira-search-results-limit-on-the-issue-navigator-357696242.html
