SharePoint - Package and deploy advice

Hi,

I am just deploying a solution from our test environment to live which deployed OK.

However, I have had to make a change to a column name on the Sharepoint List on Test, and i have regenerated the list SO as I would normally do. And have repackaged the solution with the change.

I have also made the name change to the SharePoint list on our live envionment so that it matches, but I'm unsure whether I need to 'regenerate' the SM on live via the SP List settings application aswell? Or with the New package do this automatically and there is no need for me to do this manually?

I don;t want to do it manually if it will put the SM's out of sync with each other?

Hope this makes sense!
