how to change a users role to admin?

[Aaron Stewart]

I need to transfer all work and projects from one person to another and I also need to change the role of the new individual to an admin role.  How do I do this?

Hello @Aaron Stewart 

Welcome to the Atlassian community.

What is your role in this Jira instance? This will impact whether or not you have enough permissions to make the specified changes.

I need to transfer all work and projects from one person to another 

Do you mean you need to change the Assignee on multiple issues from one user to another? You can do that by searching for the issues using 

assignee = originalUser

Then use the Bulk Change function and follow the wizard to modify the Assignee to the new user for all those issues.

You will only be able to complete that if:

1. You have the Global Permission Make bulk changes
2. You have the Browse Projects permission within each project where the original user is an Assignee on issues 
3. You have the Assign User permission within each project where the original user is an Assignee on issues
4. The new user has the Assignable User permission within each project where the original user is an Assignee on issues

I also need to change the role of the new individual to an admin role.  

Do you need to make the user an Administrator of individual Jira Projects, and Product Administrator for the entire Jira product, or an Organization Administrator?
