How to change resolution status of already closed issues

[Thierry Bouvet]

Hello,

I have some issues which are closed but without a resolution.

Is it possible to add a resolution (maybe with automation) ?

Thanks

Hi Thierry,

Welcome to the Atlassian Community.

Please check this article on how to set the resolution to issues that are in close status : https://confluence.atlassian.com/cloudkb/best-practices-on-using-the-resolution-field-968660796.html

Thank you

Thanks @Prachi Bolar 

But the problem is that issues are from customers (from a service portal) and so I'm looking for a solution "not visible" for my customers.

Do you think if I add a temporary transition, my customers will see the update ?
