With production org's not able to connect to other production org's via change sets I had to get creative, here is what I did.
CAUTION: When handling metadata components from a production enviornment in eclipse you must be VERY careful as you can screw things up in a hurry! I suggest playing around with this in a developer org before doing anything in production.
- Connect Eclipse to the production environment of both org's.
- When downloading a project in Eclipse, be sure to select all metadata components.
- One of your folders will be Reports.
- Open up the report you want to recreate. It will open a window, at the bottom of the page change your option from 'Design' to 'Source'
- In the instance you are going to migrating the report right click on the report folder where you want the report to appear, hover over 'New' and click the 'Other..' option.
- Under the 'XML' folder click 'XML' then 'Next'
- You can give the report the same name as the one being copied, so 'SampleReport.report' would work.
- Next you need to copy the XML code from step 4 and paste it into this new XML file you have created.
- NOTE: if the fields that are in the report are not consistent between the org's you will get errors
- Finally click save, then right click on the report folder and select 'Force.com' > 'Save to Server' and that's it!
