What happened to my work items after Migrating Company managed projects from Production to Sandbox

[Larry Lee]

I was migrated a Company managed project from Production to Sandbox as per the instructions from support.

When I went back to the project, none of the work items showed up in the Backlog, Active Sprint, or All Work sections. I was able to see them from the Timeline but had to go through the epics to do you. Using the search bar in All Work search did not come up with anything either. I was also able to find them in Lists. 

I checked some of the fields and most were added to the project like this: e.g. Test Case (migrated). 

Need help with this one. Much appreciated in advance.

Hello @Larry Lee 

Welcome to the Atlassian community.

Which support team did you contact?

Can you provide us with a copy or link to the instructions you used?

You say when you "went back to the project" information was missing. On which system (Production or Sandbox) were you viewing the project?

Hi @Trudy Claspill Trudy! Thanks for responding.

I haven't reached a support team yet. Thought I'd might find the answer here with all the SMEs!

Here's the link to the instructions I used: https://support.atlassian.com/organization-administration/docs/copy-production-data-to-sandbox/

When I went to Sandbox, all the work items were missing in the Backlog, Active Sprints, and All Work sections. I could only see the items in the Timeline and List.

So weird. Never ran into anything like this whenever I've migrated to Sandbox. It doesn't matter if someone was using the new Beta version but I was migrating from the current version of Jira, does it?
