customization transport Sourcing CLM 9.0 DEV to PRD

Hello experts, good afternoon!

I'm implementing CLM 9.0 and I wonder if all the customization that I'm making in DEV if it can be imported to PRD...

Because I was told that everything I create or develop regarding the customization, I'm not able to carry them out to

production, I have to create everything again, is this information right?

Can someone help me? If so, what is the method for transportation?

I appreciate the understanding and the attention of all.

Best Regards,

David Medeiros
